Answer:
FV= $4,948.16
Step-by-step explanation:
Giving the following information:
Number of periods (n)= 10
Interest rate (i)= 2.15% compound interest annually
Present value (PV)= 4,000
<u>To calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 4,000*(1.0215^10)
FV= $4,948.16
