Muscle mass ZaiShawn currently has:


p

He increases his muscle mass by 15%. So, the increased amount is 15% of p. That is:

15% = 15/100 = 0.15

0.15 * p , or


0.15p

This is his increased amount of muscle mass. We add it with his initial muscle mass, p.

After weight training, the total muscle mass, in pounds, of ZaiShawn is:


p+0.15p

Answer:

C
