Answer:
Mark will have $19,878.70 at the end of six years
Explanation:
Use the following formula to calculate the present value of cash flows
PV = ![A [\frac{1 - (\frac{1+g}{1+r})^n }{r - g} ]](https://tex.z-dn.net/?f=A%20%5B%5Cfrac%7B1%20-%20%28%5Cfrac%7B1%2Bg%7D%7B1%2Br%7D%29%5En%20%7D%7Br%20-%20g%7D%20%5D)
Where
A = Investment = $2,000
g = growth rate = 4%
r = 15%
n = 6
Placing values in the formula
PV = ![2,000 [\frac{1 - (\frac{1+0.06}{1+0.15})^6 }{0.15 - 0.06} ]](https://tex.z-dn.net/?f=2%2C000%20%5B%5Cfrac%7B1%20-%20%28%5Cfrac%7B1%2B0.06%7D%7B1%2B0.15%7D%29%5E6%20%7D%7B0.15%20-%200.06%7D%20%5D)
PV = $8,594.11
Now calculate the future value in order to determine the amount Mark will have at the ned of six years
Future value = 
Where
PV = $8,594.11
r = 15%
n = 6
Placing values in the formula
Future value = 
Future value = $19,878.70
