Final answer:
Ron's original monthly payments on his student loan would be $434.72, and after refinancing at a lower interest rate of 6%, his new monthly payment would be $372.32.
Step-by-step explanation:
Ron has a student loan of $52,000 with an annual interest rate of 8% which he plans to pay off in 20 years.
To calculate his monthly payments on the original loan, we can use the monthly payment table provided for a $1,000 loan.
For a 20-year loan at 8%, the monthly payment is $8.36 per $1,000.
Thus, for $52,000: $8.36 \/ $1,000 × $52,000
= $8.36 × 52
= $434.72
a) Ron's monthly payments on the original loan would be $434.72.
If Ron refinances his loan to an interest rate of 6%, we use the 6% column for a 20-year term.
The table shows a monthly payment of $7.16 per $1,000.
For $52,000: $7.16 \/ $1,000 × $52,000
= $7.16 × 52
= $372.32
b) Ron's new monthly payment after refinancing would be $372.32.
