Poonam and her friends booked 3 tennis courts at a sport complex.
Given:
Booking fees - First 2 hours - $ 8
Every additional hour or part thereof - $ 3.50
How much did they pay altogether, if they booked the tennis courts from 9.30 a.m. to 3.00 p.m.?

Answer: C. $ 66

Total time: 9:30 a.m. to 3:00 p.m. = 5.5 hours.
Cost per court: First 2 hours ($8) + next 4 hours ($3.50 x 4 = $14) = $22.
Note: The extra 3.5 hours is charged as 4 hours due to the "part thereof" rule.
Total for 3 courts: $22 x 3 = $66
