In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the l
Ymorist [56]

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

We have to determine

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?

<h3>What formula is used to calculate the monthly payment?</h3>

The value of the monthly payment is given by;

\rm P=PV\times \dfrac{i}{1-(1+i)^{-n}}

Where,

  • PV is the present value or the amount of the loan.
  • i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
  • n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Therefore,

The value should be used for n, the number of periods over which the loan is repaid;

n = 6 years × 12 months/year = 60 months = 60 periods.

Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

A sandbox is 1 1/3 feet tall, 1 5/8 feet wide,and4 1/2 feet long. How many cubic feet of sand will it hold
Ksivusya [100]
Volume=legnth times width times height
convert all to iimporper fractions first for ease
1 and 1/3=1+1/3=3/3+1/3=4/3

1 and 5/8=1+5/8=8/8+5/8=13/8

4 and 1/2=4+1/2=8/2+1/2=9/2

multiply them
volume=(4/3) times (13/8) times (9/2)
volume=(4 times 13 times 9)/(3 times 8 times 2)
volume=468/48
volume=39/4
volume=9 and 3/4 cubic feet
