Question

If a game costs $36.00 when it is on sale for 10% off, what is its original cost?

Answer 1

$40.00

Explanation:

Answer 2

Original cost = $40

Explanation:

Let the original cost be $x.

Therefore,

`x - (10)/(100) * x = 36 \\ \\ x - (1)/(10) x = 36 \\ (10x - x)/(10) = 36 \\ (9x)/(10) = 36 \\ 9x = 360 \\ x = (360)/(9) \\ x = \$ 40`
