Emmy's Laptop Purchase: A Math Problem

Emmy just bought a new laptop, and she's excited to start using it. However, she's also interested in learning more about the math behind her purchase. Specifically, she wants to know how much she saved by using a student discount code. In this article, we'll explore the math behind Emmy's laptop purchase and calculate the amount she saved.

The Original Price

The original price of the laptop was not specified in the problem. However, we can assume that it was a certain amount, let's call it x. We know that Emmy used a student discount code that took $50.75 off the original price, which means the discounted price is x - 50.75.

The Discounted Price

The discounted price of the laptop was $349.24. We can set up an equation to represent this:

x - 50.75 = 349.24

Solving for x

To solve for x, we need to isolate the variable x. We can do this by adding 50.75 to both sides of the equation:

x = 349.24 + 50.75

x = 400.00

Calculating the Amount Saved

Now that we know the original price of the laptop, we can calculate the amount Emmy saved by using the student discount code. We can do this by subtracting the discounted price from the original price:

Amount saved = Original price - Discounted price Amount saved = 400.00 - 349.24 Amount saved = 50.76

In this article, we explored the math behind Emmy's laptop purchase. We calculated the original price of the laptop, which was $400.00, and the amount Emmy saved by using a student discount code, which was $50.76. This problem demonstrates the importance of understanding basic algebra and how it can be applied to real-world scenarios.

Emmy's Laptop Purchase: A Math Problem Q&A

In our previous article, we explored the math behind Emmy's laptop purchase. We calculated the original price of the laptop, which was $400.00, and the amount Emmy saved by using a student discount code, which was $50.76. In this article, we'll answer some frequently asked questions about the math behind Emmy's laptop purchase.

Q: What is the formula for calculating the discounted price?

A: The formula for calculating the discounted price is:

Discounted price = Original price - Discount amount

In this case, the original price was $400.00, and the discount amount was $50.75, so the discounted price is:

Discounted price = $400.00 - $50.75 Discounted price = $349.24

Q: How do I calculate the amount saved?

A: To calculate the amount saved, you need to subtract the discounted price from the original price. In this case, the amount saved is:

Amount saved = Original price - Discounted price Amount saved = $400.00 - $349.24 Amount saved = $50.76

Q: What if I don't know the original price?

A: If you don't know the original price, you can't calculate the amount saved. However, you can still calculate the discount percentage by dividing the discount amount by the discounted price and multiplying by 100.

Discount percentage = (Discount amount / Discounted price) x 100 Discount percentage = ($50.75 / $349.24) x 100 Discount percentage = 14.53%

Q: How do I calculate the discount percentage?

A: To calculate the discount percentage, you need to divide the discount amount by the discounted price and multiply by 100.

Discount percentage = (Discount amount / Discounted price) x 100

Q: What if I have a coupon code with a percentage discount?

A: If you have a coupon code with a percentage discount, you need to calculate the discount amount by multiplying the original price by the discount percentage.

Discount amount = Original price x Discount percentage Discount amount = $400.00 x 0.1453 Discount amount = $57.81

Then, you can subtract the discount amount from the original price to get the discounted price.

Discounted price = Original price - Discount amount Discounted price = $400.00 - $57.81 Discounted price = $342.19

Q: How do I calculate the amount saved with a percentage discount?

A: To calculate the amount saved with a percentage discount, you need to subtract the discounted price from the original price.

Amount saved = Original price - Discounted price Amount saved = $400.00 - $342.19 Amount saved = $57.81
