Work out the percentage change when a price of £160 is decreased to £100.

37.5%

Step-by-step explanation:

100/160 = 0.625

1 - 0.625 = 0.375

To get the percentage from a decimal, multiply by 100:

(0.375) 100 = 37.5%

To check you work just multiply 0.375 or 37.5% with 160 and then subtract that product from 160 and it should equal 100:

(0.375) 160 = 60

160 - 60 = 100

The answer is 37.5 percent
