Vikentia [17]

Answer:

<em>The month-to-month contract will cost an extra $1356.</em>

Step-by-step explanation:

If you stay the whole year, and you pay $502 per month, you pay 12 * $502 = $6024 for the entire year.

"The month-to-month contract is $615.00/month."

If you stay the entire year, you pay 12 * $615 = $7380.

The difference is $7380 - $6024 = $1356
