Final answer:
To calculate the single payment required to pay off the three debts, we can use the present value formula. The present value of each debt can be calculated using the formula: Present Value = Future Value / (1 + Interest Rate)^Number of periods. Adding up these present values gives us the total single payment required.
Step-by-step explanation:
To calculate the single payment required to pay off the three debts, we can use the present value formula. The present value of each debt can be calculated using the formula:
Present Value = Future Value / (1 + Interest Rate)Number of periods
For the first debt, the present value is $1720 / (1 + 0.075)4 = $1496.51. For the second debt, the present value is $1315 / (1 + 0.075)5 = $1132.28. And for the third debt, the present value is $1640 / (1 + 0.075)7 = $1343.94. Adding up these present values gives us the total single payment required: $1496.51 + $1132.28 + $1343.94 = $3972.73.
