Market research indicates that at most 280 of the 65\" sets and 70 of the 55" sets can be sold per month. The maximum number of work-hours available is 3,500 per month. A 65" set requires 20 work-hours and a 55\" set requires 10 work-hours. Each 65\" set sold produces a prot of $270 and each 55" set produces a prot of $180. A wholesaler has agreed to purchase all the television sets produced if the numbers do not exceed the maxima indicated by the market research.
