Here we are trying to find the interest rate when we know the PV and FV.

Using the FV equation:

FV = PV (1 + r)

$5 = $4 (1 + r)

r = 5/4 - 1

= 25% per week

The interest rate is 25% per week.

To find the APR, we multiply this rate by the number of weeks in a year, so:

APR = (52) x 25%

= 1300%
