The correct answer is:
Each late fee was $10.
Explanation:
Clark lost $40 from 4 late fees. To find out the amount of each late fee, we divide:
40/4 = 10
This means each late fee was $10.
The charge of one late fee is -$10.
Given that,
We need to find out the charge of one late fee.
So, the following formula should be used
[tex]= \frac{Total\ late\ fees}{number\ of\ late\ fees} \\\\= \frac{-\$40}{4}[/tex]
= -$10
Therefore we can conclude that the charge of one late fee is -$10.
