3. A small generator burns two types of fuel: LOW SULFUR and HIGH SULFUR, to produce electricity. For one hour, each gallon of low sulfur emits 6 units of sulfur dioxide, generates 5 kilowatts electricity and cost Potltl. Each gallon of high sulfur emits 3 units of sulfur dioxide, generates 4 kilowatts and cost P. The environmental protection agency insists that the maximum amount of sulfur dioxide that can be emitted per hour is 15 units. Suppose that at least lo kilowatts must be generated per hour, hoe.r many gallons of low sulfur and how many gallons of high sulfur must he utilized per hour in order to minimize the cost of fuel
