1 Amanda increased the amount of protein she eats every day from 48 g to 54 g. By what percentage did Amanda increase the amount of protein she eats?

Please show your work.

A) 11.1%

B) 88.9%

C) 112.5%

D) 12.5%

Work Shown:

A = old amount = 48

B = new amount = 54

C = percent change

C = [(B-A)/A]*100%

C = [(54-48)/48]*100%

C = [6/48]*100%

C = 0.125*100%

C = 12.5%

The value of C is positive to indicate a percent increase.

So we have a 12.5% increase.

Note how 12.5% of 48 is 0.125*48 = 6

A 12.5% increase of 48 means we have an increase of 6

So, 48+6 = 54, which matches with what the instructions say. This confirms the answer.

As a shortcut, we could check it by saying 1.125*48 = 54
