Final answer:
The present value of the debt in transaction (a) is $113,222.81.
Step-by-step explanation:
To determine the present value of the debt in transaction (a), we need to calculate the present value of the promised payments of $7,200 at the end of each year for seven years and the one-time payment of $117,400 at the end of the 7th year. To calculate the present value, we can use the present value of an annuity (PVA) formula and the present value of a future amount (PVF) formula.
For the promised payments of $7,200 for seven years, we can use the PVA formula:
PVA = Payment x [1 - (1 + r)^(-n)] / r
Using the formula with a payment of $7,200, an interest rate of 7%, and a number of periods (n) of 7, we find:
PVA = $7,200 x [1 - (1 + 0.07)^(-7)] / 0.07 = $35,210.60
For the one-time payment of $117,400 at the end of the 7th year, we can use the PVF formula:
PVF = Future Amount / (1 + r)^n
Using the formula with a future amount of $117,400, an interest rate of 7%, and a number of periods (n) of 7, we find:
PVF = $117,400 / (1 + 0.07)^7 = $78,012.21
To find the present value of the debt, we add the present values of the promised payments and the one-time payment:
Present Value of Debt = $35,210.60 + $78,012.21 = $113,222.81
