Question

Mel needs to park his car for 8 hours.  Spike’s charges $5.00 per hour for the first hours and $3.00 for each 30 minutes after.  Main Deck charges $18.00 for the first 4 hours and $2.00 for every 15 minutes after.  Which garage will be less​

Answer 1

Its equal; well specify what "first hours" means but, here we go.

Explanation:

Assuming that the first hours are the 8 hours, multiply 8 by 5 to get $40

Main Deck charges $18 for 4 hours which multiplied by 2 will be $36. Then 2x2=4. $4 per hour after that. With a grand total of $40

Let me know if I'm wrong, I'm trying to improve as I go!
