Question

What single percentage change is equivalent to a 12% increase followed by a 13% increase?

Answer 1

A 26.56% increase.

Explanation:

A 12% increase corresponds to a total of 112% of the original amount.

Hence, a 13% increase of the 112% of the original amount would be equal to 1.12*1.13 = 1.2656, which equates to 126.56% of the original amount.

Hence, the single percentage change would be a 26.56% increase.
