Charmaine bought a pair of shoes at a 30% discount and paid $22.50 less than the original price. What was the original price of the pair of shoes?
A. $60
B. $68
C. $72
D. $75
E. $81
The OA is D.
Let original price be = x.
Price after 30% discount = 70% of x = x - $22.50
0.7x = x - 22.50
0.3x = 22.50
x = 22.50/0.3 = $75.
Has anyone another strategic approach to solve this PS question? Regards!

0.7p = p - 22.5
22.5 = 0.3p
p = 22.5/0.3 = 225/3 = 75
