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)^{16}
