Answer:
The value that represented with a negative number is the $10 fee that Ryan pay as a late fee.
Step-by-step explanation:
Consider the provided information.
Ryan pays his car insurance for the year in full, he will get a credit of $28.
Here credit represented with a positive number because $28 added to his account.
If he chooses to pay a monthly premium, he will pay a $10 late fee for any month the payment is late.
Here late fee represented by a negative number because if he will miss his monthly payment then $10 will be subtracted from his account.
Thus, we can say that the value that represented with a negative number is the $10 fee that Ryan pay as a late fee.
