Answer: $93,088
Explanation:
Rate is compounded monthly which makes it:
= 8% / 12
= 0.6667%
= 0.006667
The payment of $20,156 is to increase yearly at a rate of 5%. Payments are at the beginning of the period so the first payment does not have to be discounted.
[tex]= 20,156 + \frac{20,156 * 1.04}{(1 + 0.006667)^{12} } + \frac{20,156 * 1.04^{2} }{(1 + 0.006667)^{24} } + \frac{20,156 * 1.04^{3} }{(1 + 0.006667)^{36} } + \frac{20,156 * 1.04^{4} }{(1 + 0.006667)^{48} }\\\\= 20,156 + 19,355.65 + 18,587.08 + 17,849.02 + 17,140.27\\\\= 93,088.02[/tex]
= $93,088
