Hello,
This is how i got the answer...
As stated:
First hour is $8
The next 5 hours is $5 per hour
( which means, 2nd hour, 3rd hour,4th hour,5th hour,6th hour is $5 each )
Half and hour (after the 5 hours) is $2
(1 hour = 60 mins , Half and hour = 30 mins)
Hour 1 - first hour - $8
Hour 2 - $5
Hour 3 - $5
Hour 4 - $5
Hour 5 - $5
Hour 6 - $5
Hour 7 - 30mins + 30mins - $2 + $2 = $4
Hour 8 - 30mins + 30mins - $2 + $2 = $4
Total = 8+5+5+5+5+5+4+4 = ____
