Answer:
In order to evaluate a function, replace the input variable (the number or expression given) (place holder, x). Replace the x by the number or word.
Step-by-step explanation:
20% of $720( original cost)= $144 (discount)
$720- $ 144 = $576 (discounted cost)

20% of $612=$122.40 (deposit cost?)
