Answer:
$2,980.4
Explanation:
To find the answer, we use the future value of an investment formula:
FV = PV(1 + i)^n
Where:
For the first $640:
FV = $640(1 + 0.0760)^1
FV = $688.6
For the $690
FV = $688.6 + $690 (1 + 0.0760)^1
FV = $1,431
For the second $690
FV = $1,431 + $690 (1 + 0.0760)^1
FV = $2,173.4
For the final $750
FV = $2,173.4 + $750 (1 + 0.0760)^1
FV = $2,980.4
So at the end of four years, you will have $2,980.4.
