FINAL JEOPARDY: One bus for OSS costs $35.30 per hour plus $0.38 per mile. The distance from Blandford to the camp is 75 miles. The total time it takes for a bus to drive to camp, unload, and then drive back to Rowland Heights is 5 hours (we pay for students to ride to camp AND the bus to drive back home empty). Write a rational number to represent the change in Blandford's bank account balance after the three buses drop us off on Monday.
The change in our balance was -$700.50 ($176.50 for 5 hours + $57 for 150 miles = $233.50 per bus. Since we had 3 buses, the total cost was $700.50).
