Question

The original cost of a shirt was £40. It was reduced to £32.80 in a sale.

Calculate the percentage decrease.

Answer 1

18% decrease

Explanation:

-Subtract the ending value from the starting value.

40.00 - 32.80 = 7.20

-Divide this number by the starting value.

7.20 / 40.00 = 0.18

-Multiply by 100 to find the percentage change

0.18 * 100 = 18% decrease
