document.write( "Question 290984: Trucking company needs to move 21 tons of gravel. You have 8 qualified drivers in the company and two types of trucks. One type can haul 5 tons. The other can haul 3 tons. An insurance requirement specifies that 5-ton trucks must have two drivers in the cab. 3 ton trucks only need one driver. Set up two equations for this problem. One to represent the drivers and one to represent the amount of tonnage hauled. Let X represent the number of 5-ton trucks and y the number of 3 ton trucks. Solve for x and y that will satisfy both equations. That is, determine how many of each size of truck should be used to move the gravel in one trip, using all available drivers. \n" ); document.write( "
