To find the difference in payment if you stay the whole year, we first calculate the total cost for both contracts over the year.
-
Annual contract:
Monthly cost = $502.00
Annual cost = $502.00 × 12 = $6,024.00 -
Month-to-month contract:
Monthly cost = $615.00
Annual cost = $615.00 × 12 = $7,380.00
Next, we find the difference in payment between the two contracts if you stay the whole year.
Difference = Month-to-month cost - Annual contract cost
Difference = $7,380.00 - $6,024.00 = $1,356.00
Thus, the difference in payment if you stay the whole year is $1,356.00.
