Question 200

Multiple Choice

A store sells two models of laptop computers.Because of the demand, the store stocks at least twice as many units of model A as of model B.The costs to the store for the two models are $800 and $1200, respectively.The management does not want more than $29,000 in computer inventory at any one time, and it wants at least four model A laptop computers and two model B laptop computers in inventory at all times.Find and graph a system of inequalities describing all possible inventory levels.
