2. Three car models are manufactured and sold by D' Car Company: Alpha car, Beta car, and the Omega car. 50 hours of machine time and 45 hours of labor is required by each Alpha car. 58 hours of machine time and 35 hours of labor is required by each Beta car. The Omega car needs 47 hours of machine time and 40 hours of labor. The company expects to have 150 available machine time and 115 labor hours available during the next cycle of production. Alpha car is sold at $2525 and $3800 for each Beta car, and $5500 for each Omega car. We will let X1 represent Alpha, X2 to represent Beta and X3 to represent Omega.

Mathematically state the objective of maximizing profit.

a.MAX = (50X1 + 45X1) + (58X2 + 35X2) +(47X3 + 40X2)

b.MAX = 2525X1 + 3800X2 + 5500X3 + 95 + 90 + 87

c.MAX = 2525X1 + 3800X2 + 5500X3

d.MAX = (50X1 + 45X1 + 2525X1) + (58X2 + 35X2 + 3800X2) +(47X3 + 40X2 + 5500X3)
