Question 896457
 A large school district has 300 school buses. 
If each school bus is used 3 hours each day, the average speed of the school buses is 15 mi/h, and the fuel economy of the buses is 10 mi/gal.
 How much does it cost to run these buses in 22 school days if gasoline costs $1.20 a gallon?
{{{(300*3*15*22)/10}}} * 1.20 = $35,640
