Answer:
The amount of his quarterly check is $1,439,900.81.
Step-by-step explanation:
Note: The data on the salary structure offered in the question are merged together. They are therefore sorted before answering the question as follows:
Time Salary
0 $ 5,700,000
1 $ 4,300,000
2 $ 4,800,000
3 $ 5,300,000
4 $ 6,700,000
5 $ 7,400,000
6 $ 8,200,000
The explanation of the answer is now given as follows:
The amount of his quarterly check can be calculated using the following 4 steps:
Step 1: Calculation of effective annual rate (EAR)
Note: There is a need to calculate this because the interest rate in the question is compounded daily.
The effective annual rate (EAR) can be calculated using the following formula:
EAR = ((1 + (i / n))^n) - 1 .............................(1)
Where;
i = Interest rate = 4.7%, or 0.047
n = Number of compounding days in a year = 365
Substituting the values into equation (1), we have:
EAR = ((1 + (0.047 / 365))^365) - 1
EAR = 0.0481188377107922, or 4.81188377107922%
Step 2: Calculation of present of the cash of the contract offer
PV of the cash flow of the contract offer = ($5,700,000 / (1 + EAR)^Time) + ($4,300,000 / (1 + EAR)^Time) + ($4,800,000 / (1 + EAR)^Time) + ($5,300,000 (1 + EAR)^Time) + ($6,700,000 / (1 + EAR)^Time) + ($7,400,000 / (1 + EAR)^Time) + ($8,200,000 / (1 + EAR)^Time)
PV of the cash flow of the contract offer = ($5,700,000 / (1 + 0.0481188377107922)^0) + ($4,300,000 / (1 + 0.0481188377107922)^1) + ($4,800,000 / (1 + 0.0481188377107922)^2) + ($5,300,000 (1 + 0.0481188377107922)^3) + ($6,700,000 / (1 + 0.0481188377107922)^4) + ($7,400,000 / (1 + 0.0481188377107922)^5) + ($8,200,000 / (1 + 0.0481188377107922)^6)
PV of the cash flow of the contract offer = $37,861,722.19
Step 3: Calculation of present of the new contract
PV of the new contract = PV of the cash flow of the contract offer - Signing bonus payable today + Contract value increase = $37,861,722.19 - $9,200,000 + $1,200,000 = $29,861,722.19
Step 4: Calculation of quarterly check
Since the first paycheck is three months from now, this can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (2)
Where;
PV = PV of the new contract = $29,861,722.19
P = Quarterly check = ?
r = Quarterly interest rate = EAR / Number of quarters in a year = 0.0481188377107922 / 4 = 0.012029709427698
n = number of quarters = number of years * Number of quarters in a year = 6 * 4 = 24
Substitute the values into equation (2) and solve for P, we have:
$29,861,722.19 = P * ((1 - (1 / (1 + 0.012029709427698))^24) / 0.012029709427698)
$29,861,722.19 = P * 20.738735546182
P = $29,861,722.19 / 20.738735546182
P = $1,439,900.81
Therefore, the amount of his quarterly check is $1,439,900.81.
