A slot machine in a Las Vegas casino has an average profit of $600 for each 8-hour shift for the five days Sunday through Thursday, inclusive. If the average per-shift profit on Friday and Saturday is 25% greater than on the other days of the week and the slot machine is in operation every hour of every day, what is the total weekly profit that the casino makes from the slot machine?  Choose the correct answer.
A) a - 4500	B) b - 9000	C) c - 13,500	D) d - 15,500	E) e - 27,000
Correct answer is C - 13500.   Total profit per weekday = $600 X 3 (shifts)= $1800   Total profit per week (apart from SaturdaySunday) = $1800 X 5 = $9000   Total profit per shift on weekends = $600 X 125/100 = $750   Total profit on weekends = $750 X 3 (shifts) X 2 (Saturday, Sunday) = $4500.   Hence the answer is - $4500 + $9000 = $13,500. (c - 13,500)
