What is the price if you mark up $50 by 10%
BARSIC [14]

Answer:

55

Step-by-step explanation:

Original price = 50 and percent markup is 10%

The increase is the original price times the percent markup

increase = 50 * 10%

increase  = 50*.10

                = 5

The new price is the original price plus the increase

new price = 50 + 5

                 = 55
