r = 43.35

Step-by-step explanation:

Given

$Current\ Rent = r$

$Increment = 15\%$

$New\ Rent = \$51$

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

$\%Increment = \frac{New\ Rent - Current\ Rent}{Current\ Rent}$

Substitute values in the above equation

$15\% = \frac{51 - r}{51}$

Cross Multiply

$51 - r = 15\% * 51$

Convert percentage to decimal

51 - r = 0.15 * 51

51 - r = 7.65

And the value of $r\ is\ calculated\ using:$

r = 51 -7.65

r = 43.35

Hence, Cody's current rent is $43.35 monthly
