Question

Mark bought a plane ticket for $234, which was 80% of the original price. How much was the original price?

A) $292.5
B) $314
C) $154
D) $187.2

Answer 1

let
x---------> original price

we know that
x*0.80=$234-------> divide by 0.80 both sides
x=234/0.80
x=$292.5

the answer is
$292.5

Answer 2

A) $292.5

Explanation:

Let x represent the original price. 80% of x is found by multiplying by 0.8:

0.8x = 234

Divide both sides by 0.8:

0.8x/0.8 = 234/0.8

x = 292.5
