A. $7.17

Step-by-step explanation:

Given: The cost of compressor P= $477.95

The monthly interest rate = 1.5 %

In decimal, the monthly interest rate r=0.015

Now, The charge be at the end of the first month is given by:-

$I=Pr\\\Rightarrow\ I=477.95\times477.95\\\Rightarrow\ I=7.16925\approx7.17$

Hence, the charge be at the end of the first month is $7.17.
