Two models of a product - Regular (X) and Deluxe (1) - are produced by a company. A linear programming model is used to determine the production schedule, while maximizing the total revenue from sales. The formulation is as follows: Maximize 100 X + 200Y Subject to: earnsomenews (labor hours) mmmmmmnews (plastic, raw material) mummum (steel, raw material) Xa0 Y20 The solution of the model is given below.

As an operations manager, your task is to hire a number of part-time labor to make things work again. If each part-time labor can only work 10 hours, how many part-time labor you need to hire in order to meet sales revenue target given in the LP model solution? AJ 4.6 B) 4 9 15
