Please program this using IBM ILOG CPLEX. I already have the answer in lingo and hence i do not want a lingo solution. i need it in CPLEX (OPLIDE)

a company owns four production plants at which personal computers are produced. it can sell up to 20,000 computers per year at a price of $3500 per computer. For each plant, the production capacity, the production cost per computer, and the fixed cost of operating a plant for a year are given in the table below:

Determine how many computers it. should produce at each plant in order to maximize its yearly revenue.(Note that if no computers are produced by a plant during the year, Comquat need not pay the fixed cost of operating the plant that year.)
