Answer: Making 24 payments of $95.
Explanation:
This problem is really just simple multiplication. (and maybe a bit of subtraction)
First, you multiply 24 by $95, which would give you $2,280.
Then, multiply 30 by $80, which would give you $2,400.
This would give you the answer to your first question.
Finally, subtract $2,400 from $2,280 to get $120, which is your answer to the second question.
