Introduction

Sage is a fashion-conscious individual who loves to stay up-to-date with the latest trends. She has been eyeing three new dresses that she wants to add to her wardrobe. However, she is faced with a dilemma - two stores, A and B, are offering different discounts on the dresses. In this article, we will analyze the offers from both stores and determine which one offers the best sale price on the dresses.

Store A's Offer

Store A is offering a "buy 2 dresses, get the third dress free" deal. This means that if Sage buys two dresses at the regular price of $75 each, she will get the third dress for free. To calculate the total cost of the dresses, we need to first find the cost of two dresses.

Cost of Two Dresses

The cost of two dresses at the regular price of $75 each is:

2 x $75 = $150

Since the third dress is free, the total cost of the three dresses at Store A is:

$150 + $0 = $150

Store B's Offer

Store B is offering a 30% discount on the total price of the dresses. To calculate the total cost of the dresses, we need to first find the total price of the three dresses at the regular price.

Total Price of Three Dresses

The total price of three dresses at the regular price of $75 each is:

3 x $75 = $225

Since Store B is offering a 30% discount, we need to calculate the discount amount.

Discount Amount

The discount amount is 30% of the total price of the dresses:

30% of $225 = 0.30 x $225 = $67.50

Total Cost at Store B

The total cost of the dresses at Store B after the discount is:

$225 - $67.50 = $157.50

Comparison of Offers

Now that we have calculated the total cost of the dresses at both stores, we can compare the offers.

Store	Total Cost
Store A	$150
Store B	$157.50

Conclusion

Based on the calculations, we can see that Store A offers the best sale price on the dresses. The total cost of the dresses at Store A is $150, which is $7.50 less than the total cost at Store B. Therefore, Sage should consider buying the dresses at Store A to get the best deal.

Mathematical Concepts Used

This problem involves the following mathematical concepts:

Discount: A discount is a reduction in the price of an item. In this problem, Store B is offering a 30% discount on the total price of the dresses.
Percentage: A percentage is a way of expressing a value as a fraction of 100. In this problem, the discount amount is 30% of the total price of the dresses.
Subtraction: Subtraction is a mathematical operation that involves finding the difference between two numbers. In this problem, we need to subtract the discount amount from the total price of the dresses to find the total cost at Store B.

Real-World Applications

This problem has real-world applications in the following areas:

Retail: Retailers often offer discounts and promotions to attract customers. This problem demonstrates how to calculate the total cost of items after a discount.

Introduction

In our previous article, we analyzed the offers from two stores, A and B, and determined that Store A offers the best sale price on the dresses. However, we received many questions from readers who wanted to know more about the problem. In this article, we will answer some of the most frequently asked questions about the problem.

Q: What if the prices of the dresses are different at Store A and Store B?

A: If the prices of the dresses are different at Store A and Store B, we would need to calculate the total cost of the dresses at each store separately. Let's say the prices of the dresses at Store A are $75, $80, and $85, and the prices of the dresses at Store B are $70, $75, and $80. We would need to calculate the total cost of the dresses at each store using the same method as before.

Q: What if Store A is offering a different discount on the dresses?

A: If Store A is offering a different discount on the dresses, we would need to calculate the total cost of the dresses at Store A using the new discount. Let's say Store A is offering a 20% discount on the total price of the dresses. We would need to calculate the discount amount and subtract it from the total price of the dresses to find the total cost.

Q: What if Store B is offering multiple discounts on the dresses?

A: If Store B is offering multiple discounts on the dresses, we would need to calculate the total cost of the dresses at Store B using the new discounts. Let's say Store B is offering a 20% discount on the first dress, a 15% discount on the second dress, and a 10% discount on the third dress. We would need to calculate the discount amount for each dress and subtract it from the price of each dress to find the total cost.

Q: How do I calculate the total cost of the dresses if I'm buying multiple items?

A: To calculate the total cost of the dresses if you're buying multiple items, you would need to follow these steps:

Calculate the total price of the items at the regular price.
Calculate the discount amount for each item.
Subtract the discount amount from the price of each item to find the discounted price.
Add up the discounted prices of all the items to find the total cost.

Q: What if I'm buying items with different prices and different discounts?

A: If you're buying items with different prices and different discounts, you would need to calculate the total cost of each item separately using the same method as before. Then, you would need to add up the total costs of all the items to find the overall total cost.

Q: How do I know which store offers the best sale price?

A: To determine which store offers the best sale price, you would need to calculate the total cost of the dresses at each store using the same method as before. Then, you would need to compare the total costs of the dresses at each store to find the lowest price.

Q: What if I'm buying items with different quantities?

A: If you're buying items with different quantities, you would need to calculate the total cost of each item separately using the same method as before. Then, you would need to add up the total costs of all the items to find the overall total cost.
