Question

Rosemarie went to the store and bought some eyeliner for 7.70. two weeks later the price of the eyeliner was increased 60%

what was the new price of the eyeliner?

Answer 1

Answer:

Concept: Percentage Addition

1. Your original price is 7.70
2. It increased by 60%
3. Hence you do 7.70 * .60 = x
4. Whatever you get from (3) you add it to 7.70+x to get your final price

Answer 2

7.7x60/100 = 426/100 = .426

7.7 + .426 = 8.126
