The number of periods over which interest is calculated on the loan.
We have to determine
The following formula is used to calculate the monthly payment on a personal loan.
<h3>What is the formula used to calculate monthly payments?</h3>The formula used to calculate monthly payments are as follows;
Where,
1. PV is the present value or the amount of the loan.
2. 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.
3. 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.
Hence, the number of periods over which interest is calculated on the loan.

Step-by-step explanation:
(a)
Given y is inversely proportional to x² then the equation relating them is
y = ← k is the constant of variation
To find k use any ordered pair from the table.
Using (1, 4 ) , then
4 = =
( multiply both sides by 1
4 = k
y = ← equation of variation
(b)
When y = 25 , then
25 = ( multiply both sides by x² )
25x² = 4 ( divide both sides by 25 )
x² = ( take the square root of both sides )
x = ± = ±
Since x > 0 then x =
