Step-by-step explanation:
Formula describing the situation:
x = t - yz
where
x = amount down
y = money paid each month
z = number of months
t = total price
To rewrite the formula to solve for the amount of money Jeremy must pay each month, we would make y the subject of the formula:
x = t - yz
x - t = - yz
divide both sides by -1:


AMount Jeremy must pay each month is y = (t-x)/z
