Question

Isaac purchased a pair of skates at a 15% off sale.

If he saved $19.50, what was the original price of
the skates?

Answer 1

Let
x-------------> original price of the skates

we know that
15% of x is $19.50
so
0.15x=19.50---------> x=19.50/0.15-----------> x=$130

the answer is
the original price of the skates was $130
