Question

Mary increased the amount of vitamin C she takes each day from 48 mg to 54 mg. By what percentage did Mary increase the amount of vitamin C she takes each day?

Answer 1

% CHANGE FORMULA:
(New # - Original #) ÷ Original # x 100

=(54mg - 48mg)/48mg * 100
=6/48 * 100
=0.125 * 100
=12.5% increase

Hope this helps! :)
