From the calculation done below, the interest when the rate is 9% is $101.25.

<h3>How interest is calculated using direct variation?</h3>

Since the interest on investment varies directly as the rate of interest, the relevant direct variation formula to use to calculate investment is as follows:

i = kr ................................. (1)

Where:

i = interest amount = $45

k = investment = ?

r = interest rate = 0.04

Substituting the values into equation (1) and solving for k, we have:

45 = k0.04

k = 45 / 0.04

k = $1,125

To find the interest when the rate is 9%, we substitute k = $1,125 and r = 9% into equation (1) as follows:

i = $1,125 * 9% = $101.25
