Answer 2

In Store A, a video game that regularly sells for $59.99 is on sale at 10% off. In Store B, the same video game regularly sells for $64.99 and is on sale at 15% off. Which store sells the video game for the lower sale price?

Answer 3

For Store A, the sale price would be:

Sale price = regular price - (percent off * regular price)
Sale price = 59.99 - (0.10 * 59.99)
Sale price = 53.99

For Store B, the sale price would be:

Sale price = regular price - (percent off * regular price)
Sale price = 64.99 - (0.15 * 64.99)
Sale price = 55.24

Therefore, Store A sells the video game for the lower sale price.
