Question

After a discount of 10%, the price of a pair of jeans, including tax, was $69.62. The following equation can be used to find x, the price of the pair of jeans without the discount.

x - 0.1x + 0.07(x - 0.1x) = 69.62

What is the price of the pair of jeans without the discount?

$70.58

$72.29

$74.86

$80.02

Answer 1

$72.29
I'm going to show you all the steps:
x - 0.1x + 0.07(x - 0.1x) = 69.62
x - 0.1x + 0.07x - 0.007x = 69.62
x - 0.03x - 0.007x = 69.62
x - 0.037x = 69.62
.963x = 69.62
x = 69.62/.963
x= 72.29
