yes, I saw that, but how do I get the answer on each line to compare them. Do I multiply each line, or add them.

first one:

-you multiply them, brackets mean multiplication

1.05(1.1)(1.15)

= 1.05 x 1.1 x 1.15 = 1.32825

so that is an increase of 32.825%

1.32825 is what I got for the b and 1.331 is what I got for c so I guess the answer would be c
