payment at the end of the loan period, repaying the principal and interest, what is
the total amount (F/P) that must be paid back?
a. What is the number of time periods (n) you should use in solving this problem?
b. What rate of interest (i), per period of time, should be used in solving this
problem?
c. Is the present single amount of money (P) known? (Yes, No)
d. Which time value factor should be used to solve this problem?
e. What is the total amount that must be paid back?
f. How much of the total amount repaid represents interest?
2.2 To purchase a new loader it is necessary to borrow $18,550. A vendor representative
offers a 10-yr loan at an interest rate of 5% compounded annually. If you make
annual payments at the end of each yr, repaying the principal and interest, what is
the total annuity (A/P) that must be paid back?
a. What is the number of time periods (n) you should use in solving this problem?
b. What rate of interest (i), per period of time, should be used in solving this
problem?
c. Is the present single amount of money (P) known? (Yes, No)
d. Which time value factor should be used to solve this problem?
e. What is the total annuity that must be paid back?
f. What is the value of annual payment?
2.3
The salvage value of loader is $25,000 at the end of it’s 20 yr useful life. The
bank offers a 20-yr loan at an 3% interest rate of compounded annually. If you
collect only one salvage payment at the end of the life period, collecting salvage
sales amount, what is the total amount (P/F) that will be received in present value
dollars?
a. What is the number of time periods (n) you should use in solving this problem?
b. What rate of interest (i), per period of time, should be used in solving this
problem?
c. Is the future single amount of money (F) known? (Yes, No)
d. Which time value factor should be used to solve this problem?
e. What is the total amount of salvage value present worth?
f. How much of the total amount represents interest?
