Your parents are planning to rent you an apartment when you go to college. the annual contract is $535.00/month with a 2 month penalty for breaking the lease. the month-to-month contract is $615.00/month. what is the difference in the amount paid if you leave after 8 months?

difference in amount = $430

Explanation:
1- Annual contract:
The annual contract means a contract for 12 months. There is a month penalty for breaking the lease. 
This means that, if you left after 8 months, you will have to pay for 10 month.
Total paid = monthly payment * 10
Total paid = 535 * 10 = $5350

2- Month-to-month contract:
You will only paid for the 8 months you stayed,
Total paid = monthly payment * 8
Total paid = 615 * 8 = $4920

3- Getting the difference:
We can note that a month-month contract is a better option if you intend to stay for only 8 months
Difference = 5350 - 4920 = $430

Hope this helps :)
