The amount of the loan after 11 years is $34,113.53 and the intereest earned is $4,113.53
The formula for calculating the exponential function is expressed as:
[tex]A =P(1+\frac{r}{n} )^t[/tex]
Given the following
Substitute into the formula to have:
[tex]A=30000(1+\frac{0.047}{4} )^{11}\\A =30000(1.13711)\\A =\$34,113.53[/tex]
Hence the amount of the loan after 11 years is $34,113.53
Interest = A - P
Interest = 34,113.53 - 30000
Interest = 4,113.53
Hence the intereest earned is $4,113.53
