Answer:

#3

Explanation:

from the formula given, the part "(1.025)" would be the growth factor or rate.

This part has a formula:

(1 + r)

where r is rate

So substituting, we get:


1.025 = 1 + r\\1.025 - 1 = r\\r = 0.025

So, in pecentage, we have to multiply, thus we get:

0.025 * 100 = 2.5%

Answer choice #3
