Answer:
Results are below.
Explanation:
Giving the following information:
Initial investment (PV)= $500
Number of periods (n)= 1 year
Interest rate (i)= 4% = 0.04
To calculate the future value after one year, we need to use the following formula:
FV= PV*(1+i)^n
FV= 500*(1.04^1)
FV= $520
The savings increased by $20.
