1. Calculate the payment amount for the loan in cell C15. Reference the
cells containing the appropriate loan information as the arguments for the
function you use. Cells C20-C67 in the "Payment" column are populated
with the payment amount from cell C15. [34 Points]:
=PMT(C13/12,C12,C11)
2. Calculate, in cell D20, the interest amount for period 1 by multiplying
the balance in period 0 (cell F19) by the loan interest rate (cell C13)
divided by
12. Dividing the interest rate by 12 results in the monthly interest rate. This
formula is reusable. The interest for a given period is always the monthly
interest rate times the balance from the previous period.: =F19*$C$13/12
3. Calculate, in cell E20, the principal amount for period 1. The principal
amount is the difference between the payment amount (cell C20) and the
interest amount (cell D20) for period 1. Construct your formula in such a
way that it can be reused to complete the "principal" column of the
amortization table.: C=20-D20
4. Calculate, in cell F20, the balance for period 1. The balance is the
difference between the balance for period 0 (cell F19) and the principal
amount for period 1 (cell E20). This formula is reusable. The balance is
1/9
,always calculated as the difference between the balance from the previous
period and the principal amount for the current period.: =F19-E20
5. Calculate, in cell G12, the total amount paid by multiplying the
payment amount (cell C15) by the term of the loan (cell C12).: =C15*C12
6. Calculate the total interest paid in cell G13. The total interest paid is
the sum of all interest paid in the "Interest" column of the amortization
table.: =SUM(D20:D67)
7. Check to see if the total interest calculation in the amortization
table is correct. The total interest paid is also equal to the difference
between the total amount paid over the course of the loan and the
original loan
amount. Insert a formula into cell G14 to calculate the difference between
the total amount paid and the original loan amount. Notice the negative sign
associated with the original loan amount. This value should equal the total
interest calculated using the amortization table.: =G12-ABS(C11)
8. Assume you have made the first 36 payments on your loan. You want to
trade the car in for a new car. You believe that you can sell your car for
$4000. Will this cover the balance remaining on the car in period 36?
Answer either "Yes" or "No" in cell G15 from the drop-down menu.: No
2/9
, 9. Use the HLOOKUP function to complete the "Hourly Wage" column
of table 1. Use the "Employee" column of table 1 as the lookup_value and
the "Employee Wage Information" above table 1 as your reference table.:
-
=HLOOKUP(D16,$E$11:$H$12,2,FALSE)
10. Use the AND function to complete the "Time Bonus?" column of table
1. An employee earns a time bonus if the project's "Hours Worked" are
fewer than the "Estimated Hours" and if the work "Quality" is greater
than 1.: =AND(E16<C16,H16>1)
11. Use the OR function to complete the "Outcome Bonus?" column of
table
1. An employee earns an outcome bonus if the difficulty of a job is
greater than 3 or if the quality of their work is equal to 3.:
=OR(G16>3,H16=3)
12.Use the IF function to complete the "Time Bonus $" column of table 1.
If an employee earns a time bonus (i.e., the corresponding cell in the "Time
Bonus?" column is TRUE), then "Time Bonus $" is the "Job Pay" for that
project times the bonus percentage in cell M11. Otherwise "Time Bonus $"
is 0.: =IF(I16,K16*$M$11,0)
13. Use the IF function to complete the "Outcome Bonus $" column of table
1. If an employee earns an outcome bonus (i.e., the corresponding cell in
the "Outcome Bonus?" column is TRUE), then "Outcome Bonus $" is the
"Job Pay" for that project times the outcome bonus percentage in cell
M12; otherwise, "Outcome Bonus $" is 0.: =IF(J16,K16*$M$12,0)
