Explanation:
You could use the formula
to plug in P = 1500, r = 0.02 and n = 12 to get the answer above. This is the compound interest formula. The interest rate r is divided into n = 12 to account for monthly compounding. The original exponent t turns into 12t. So for instance, if t = 2 years go by, then 12*t = 12*2 = 24 months have gone by.
we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph

Divide by both numerator and denominator
therefore
the answer is
