Question

During a store's closing sale, everything is 65% off. Victors goes into the store to buy a shirt and a pair of pants, and spends 15.40 before tax.How much would he have spent without the sale

Answer 1

$51.33

Explanation:

Everything is off 65% so that means that $15.40 if 35% of the original price(100%-65%)

Set up Equation:

`(15.40)/(x) = (30)/(100)`

Simplify:

`(15.40)/(x) =(3)/(10)`

Multiply the first numerator by the last denominator and the first denominator by the last numerator

`3x=154`

Divide 3 by both sides:

x= 51.33
