The ways that would be useful in calculating the rate of interest he will pay each year is: 6000(1.007)^12×2
Using this formula
Rate of interest=Principal(1+Rate)^nt
Where:
Principal=$6,000
Rate=0.7%
Time=2 years
Number of months =12 months
Let plug in the formula
Rate of interest=6000(1+.007)^12×2
Rate of interest=6000(1.007)^24
Rate of interest=$7,093.47
Therefore the ways that would be useful in calculating the rate of interest he will pay each year is: 6000(1.007)^12×2
