The A option is correct.
<h2>Ratio and proportion</h2>A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given
The interest rate applied to the present value has on the monthly payment P in the formula
The effect an increase in i.
<h3>How to find it?</h3>on simplifying the equation, we get
Let n be the constant, then the equation will be
It is clear that V is proportional to i.
An increase in i, the interest rate, will not change P, the monthly payment.
Thus, the A option is correct.
