Please help!!

The Acme shipping company measures production by the number m of truck-miles shipped each day. That is Q: m = truck-miles per day. {A truck-mile = 1 truck at 1 mile = 2 trucks x 35 mile = etc.) Operating expenses are paid-out for: - SW per hour for the wages of the drivers (1 driver per truck). - Sp per gallon for the fuel used by the trucks. Assume the following (hypothetical) formula describes the fuel consumed by the trucks (truck-mile fuel economy}: - g = A + B - s where g is gallons of fuel (gasoline), sis truck speed in mph [for s > 0}. Assume that Acme owns its trucks and keeps them in good operating order; it can use one, two, or more trucks depending on demands. -) How would you come-up with a math expression for costs C(s; w; p, A, B)
