The price of a hairpiece was increased from $500 to $550. what was the percent of increase? 9.1%. 10%. 20%. 25%. none of these.

Answer 1

The answer is "10%".

price of a hairpiece was increased from $500 to $550
So, the difference is = 550 - 500 = $50
original price = $500
now, divide the difference between the prices by the original price:
50/500 = 1/10
now to get percentage multiply it with 100;
1/10 x 100 = 10%
