Given that Amber borrows $1,450 from the bank.
She has two options to pay the loan amount. Pay in 3 years or in 2 years.
Calculation of interest for payment in 3 years.
Loan amount P=1450
Interest rate r=5%=0.05
Time t=3 years
Interest is compounded annually so we will use compound interest formula

Plug the given value



A=1678.55625
Interest = A-P=1678.55625-1450= 228.55625
---
Calculation of interest for payment in 2 years.
Loan amount P=1450
Interest rate r=3.5%=0.035
Time t=2 years
Interest is compounded annually so we will use compound interest formula

Plug the given value



A=1553.27625
Interest = A-P=1553.27625-1450= 103.27625
---
Now we just have to find the difference of interest in both cases
228.55625-103.27625 = 125.28
Hence final answer is approx $125.
