Question

a pair of jeans originally cost $140 and are now on sale for 65% off. what is the sale price of the jeans

Answer 1

$49

Explanation:

Method 1:

100% - 65% = 35%

`(y)/(140): (35)/(100)`

y · 100 = 35 · 140

100y = 4900

100y ÷ 100 = 4900 ÷ 100

y = 49

Method 2:

`(y)/(140): (65)/(100)`

y · 100 = 65 · 140

100y = 9100

100y ÷ 100 = 9100 ÷ 100

y = 91

$140 - $91 = $49
