The original amount of crunches Peter did was 32 and the increased amount was 36. To find the percentage increase, we can use the formula:

((New value - Original value) / Original value) * 100

Plugging in the values, we get:

((36 - 32) / 32) * 100 = (4 / 32) * 100 = 0.125 * 100 = 12.5%

Therefore, Peter increased the amount of crunches he completed by 12.5%.

The answer is B) 12.5%
