answers are: a) $2,931.45 b) $2,924.65 c) $41,600.00 d) $40,000.00

The formula is:

A = P(1 + r/n)

^{nt}Where:

A = the ending balance

P = the principle or initial balance = $2500

r = annual interest rate expressed as a decimal value = 4% = 0.04

n = number of compoundings per year = quarterly = 4

A = ($2500)(1 + 0.04/4)

^{4*4}A = ($2500)(1.01)
