A.
$140
B.
$150
C.
$160
D.
$180
Show solution
Solution
Let the original price be x. Selling Price = x - 20% of x = x - 0.2x = 0.8x. Therefore, 0.8x = 120. x = 120 / 0.8 = 150.

Show solution
Solution
Let the original price be x. Selling Price = x - 0.10x = 0.90x. So, 0.90x = 150. Therefore, x = 150 / 0.90 = 166.67, approximately $160.
