To find the percentage increase, we can use the formula:
Percentage increase = ((new value - original value) / original value) * 100
In this case, the original value is 32 and the new value is 36.
Percentage increase = ((36 - 32) / 32) * 100
= (4 / 32) * 100
= 0.125 * 100
= 12.5
Therefore, the percentage increase is 12.5%.
Answer: B) 12.5%
To find the percentage increase, we need to compute the difference between the new amount and the original amount, and then divide that difference by the original amount.
The difference between 36 and 32 is 36 - 32 = 4.
To find the percentage increase, we divide the difference by the original amount and then multiply by 100: (4 / 32) * 100 = 12.5%
Therefore, the correct answer is B) 12.5%.
