Question

Peter works in a shop an was told to increase the prices by 15%. he increased one price to £172.50. what was the original price.

Answer 1

$150

Explanation:

Increased by 15% is the same as multiplying by 115% (or 1.15)

If 172.50 is 115%, then we must multiply by 100/115.

172.50 x (100/115) = 150

$150 was the original price.
