20% can be represented as 20/100, which is 0.2. However because you are adding 20% of the value onto the while value, you do 100%+20%=120%, which is 120/100 and therefore your multiplier is 1.2. 10.2×1.2= 12.24in, so the answer is C

20%=.2

10.2*.2= 2.04

2.04+10.2
=12.24

so your answer is C. 12.24 in
