Consider the student loan information here: balance of $42,350 with proposed payment of $413, and an interest rate of 6.49% annual interest compounded monthly.

1. Using the proposed payment, determine how much the final payment will be when the loan is balanced. The loan is balanced when the remaining balance is $0.

2. Using the proposed payment, determine the remaining balance after 3 years.

3. Using the proposed payment, determine the total amount of interest paid over the entire loan.

4. Instead of the proposed payment, suppose someone increased the payment by $50 per month for the entire loan, how much interest would this save?

B) Consider investing over time, so as your salary goes up, you invest more each month. For 10 years straight, you invest $100 per month, then you invest $300 per month for 10 years, and end with $500 per month for 10 years. Over the full 30 years, you earn 4.8% annual interest compounded monthly.

1. Determine the balance at the end of the 30 years.

2. Determine the amount of money you invested total.

3. Find the amount of interest earned over the 30 years.
