Question

A plant makes aluminum and copper wire. Each pound of aluminum wire requires 7 kwh of electricity and 1/3 hr. of labor. Each pound of copper wire requires 4 kwh of electricity and 2/3 hr. of labor. Production of copper wire is restricted by the fact that raw materials are available to produce at most 60 lbs./day. Electricity is limited to 600 kwh/day and labor to 40 person–hrs./day. If the profit from aluminum wire is $.29/lb. and the profit from copper is $.38/lb., what is the maximum profit? Round corner points to the nearest tenth (e.g. 18.1) and the resulting maximum profit to the nearest cent (e.g. 43.32).
