Let the glitter-filled adventure begin!

Which Equation Represents the Situation?

Alright, guys, let's break down this glitter pen dilemma! Kylie's got a budget of $9, and each pen costs $1.50. Our mission? To find out how many pens she can buy. To do this, we'll translate the word problem into a neat little equation. This is where algebra comes in handy, and believe me, it's not as scary as it sounds! The key is to understand what each part of the problem represents. The cost per pen is $1.50, and we don't know the number of pens, so let's call that pp. The total cost will be the cost per pen multiplied by the number of pens, and that has to be equal to or less than the total amount of money Kylie has, which is $9. Now, let's formulate this into a mathematical equation. The total spent on pens can be calculated as the price per pen multiplied by the number of pens. So, if each pen costs $1.50, the total cost for pp pens is 1.50∗p1.50 * p. Since Kylie has $9 to spend, the total cost must be equal to or less than $9. This gives us the equation: 1.50p=91.50p = 9. This equation neatly captures the essence of the problem, allowing us to find out how many pens Kylie can buy. Now, let's see how this works in practice. This equation translates the word problem into mathematical terms, making it easier to solve. Now, let's explore our options to find the correct equation that fits this scenario. We've got a budget, a per-item cost, and the unknown number of items. It's like a treasure map where the 'X' marks the spot for the number of pens. Remember, the goal is to identify the relationship between the cost of each pen, the number of pens, and the total money Kylie has to spend. And with a little bit of algebraic thinking, we're going to nail it. This step is about converting words into math. Remember, the equation is your tool to crack the code and discover the solution. Always take the time to understand the components of your equation so that you can work the math with confidence.

Formulating the Equation Step-by-Step

Let's break down how we arrive at the equation. We know that each glitter pen costs $1.50. This is the price per pen. The total amount Kylie can spend is 9.00.Wedon′tknowtheexactnumberofpensKyliecanbuy,sowe′llrepresentthisunknownquantitywiththevariable′9.00. We don't know the exact number of pens Kylie can buy, so we'll represent this unknown quantity with the variable 'p

. Therefore, the equation to represent this situation is the cost per pen multiplied by the number of pens equals the total cost, which in this case means 1.50∗p=91.50 * p = 9.

The Correct Equation

So, the equation that represents this situation is 1.50p=91.50p = 9. This equation shows the relationship between the cost per pen, the number of pens Kylie can buy, and her total budget. This is the heart of our mathematical representation. The beauty of this equation is how it encapsulates the entire problem in a concise, solvable format. With this equation in hand, we're ready to move on to the next step, where we'll figure out how to find the value of 'pp', which is the number of pens Kylie can buy. It's not just about solving the equation; it's about understanding what each part means and how it reflects the real-world scenario. You are doing great, guys! Keep it up!

Which Operation Can You Use to Solve 1.50p=91.50p = 9?

Alright, now that we've got our equation, 1.50p=91.50p = 9, it's time to figure out how to solve it. This means finding the value of 'pp', the number of glitter pens Kylie can purchase. To do this, we need to use an operation that will isolate 'pp' on one side of the equation. In this case, since 'pp' is being multiplied by 1.50,weneedtoperformtheinverseoperation,whichisdivision.Divisionistheoppositeofmultiplication,justlikesubtractionistheoppositeofaddition.So,tosolvefor′1.50, we need to perform the inverse operation, which is division. Division is the opposite of multiplication, just like subtraction is the opposite of addition. So, to solve for 'p

, we'll divide both sides of the equation by 1.501.50. This maintains the balance of the equation while allowing us to find the value of 'pp'. Remember, the goal is to get 'pp' by itself. This involves understanding that to undo multiplication, you must divide. This is a fundamental concept in algebra and is crucial for solving many types of equations. When we divide both sides of an equation by the same number, we are essentially maintaining the equality. Think of it like a seesaw: to keep it balanced, any action on one side must be mirrored on the other. This ensures that the equation remains valid throughout the solving process. You want to divide both sides by 1.501.50 to isolate pp. This step is a cornerstone in solving the equation. Once you understand this principle, you can apply it to a wide range of problems, not just this glitter pen scenario. This process is like unlocking a secret code. You are simply applying the correct operation to both sides of the equation to reveal the solution. Awesome work so far!

Applying the Inverse Operation

So, to solve the equation 1.50p=91.50p = 9, you would divide both sides by 1.501.50. This can be written as:

This division will isolate 'pp' and reveal the number of pens Kylie can buy.

Understanding the Inverse Relationship

The reason we use division here is because it's the inverse operation of multiplication. It 'undoes' the multiplication, allowing us to find the value of 'pp'. This is a fundamental principle in algebra.

How Many Pens Can Kylie Buy?

Okay, guys, it's time for the grand finale! We've formulated the equation, identified the correct operation, and now it's time to find out how many glitter pens Kylie can actually buy. Let's recap: our equation is 1.50p=91.50p = 9. We know we need to divide both sides by 1.501.50 to solve for pp. So, let's do the math: 9/1.50=69 / 1.50 = 6. Therefore, p=6p = 6. This means Kylie can buy 6 glitter pens with her $9 budget. See? Math can be both practical and fun! This is where all the previous steps come together to give us a real-world answer. We transformed a shopping scenario into a mathematical problem and solved it using algebra. Think of this as the final flourish of our math adventure. You've not only solved an equation but also applied math to a real-life situation. Now you know how to use math to plan a party! This isn't just about getting the answer; it's about understanding how to use math in everyday life. We translated a word problem, crafted an equation, selected the right operation, and found the solution. You should be super proud of yourself! The next time you're out shopping, you can use these skills to budget and make smart decisions. Congratulations, math whizzes! You've successfully completed the glitter pen challenge.

Calculating the Final Answer

By dividing 9 by 1.50, we found that p=6p = 6. Therefore, Kylie can buy 6 glitter pens. This number represents the total number of pens Kylie can purchase without exceeding her budget.

Wrapping it Up

Kylie can buy 6 glitter pens. We solved the problem using the equation 1.50p=91.50p = 9 and the operation of division. Awesome, right? You are totally amazing! This shows you how math can be both fun and useful in everyday situations. Keep practicing and applying these skills, and you will become a math master in no time!
