Question

You have a coupon for $15 off a video game. You can use it on 2 separate days.

Answer 1

a) Original price of the game is $ 37.99

b) Percent of discount is 39 %

c) Original price is $ 27.99

d) Percent of discount is 54 %

Solution:

You have a coupon for $15 off a video game

a) On Monday, the discounted price of your video game is $22.99

Therefore,

Discount price = $ 22.99

From given,

Discount rate = $ 15

Therefore,

Original price = Discount price + Discount rate

Original price = 22.99 + 15 = 37.99

Thus original price of the game is $ 37.99

b. What is the percent of discount to the nearest percent?

Let "x" be the percent of discount

Then, we can say,

x % of original price = discount rate

x % of 37.99 = 15

$\frac{x}{100} \times 37.99 = 15\\\\x \times 37.99 = 1500\\\\x = \frac{1500}{37.99}\\\\x = 39.48 \approx 39$

Thus percent of discount is 39 %

c. On Thursday, the discounted price of your video game is $12.99

Original price = 12.99 + 15 = 27.99

Thus original price is $ 27.99

d. What is the percent of discount to the nearest percent?

Let "x" be the percent of discount

Then, we can say,

x % of original price = discount rate

x % of 27.99 = 15

$\frac{x}{100} \times 27.99 = 15\\\\x \times 27.99 = 1500\\\\x = \frac{1500}{27.99}\\\\x = 53.5 \approx 54$

Thus percent of discount is 54 %
