Solve the problem.A company manufactures two products. For $1.00 worth of product A, the company spends $0.50 on materials, $0.20 on labor, and $0.15 on overhead. For $1.00 worth of product B, the company spends $0.45 on materials, $0.20 on labor, and $0.15 on overhead. Let a = 
and b = 
.Then a and b represent the "costs per dollar of income" for the two products.Suppose the company manufactures x1 dollars worth of product A and x2 dollars worth of product B and that its total costs for materials are $140, its total costs for labor are $60, and its total costs for
overhead are $45. Determine x1 and x2, the dollars worth of each product produced. Include a vector equation as part of your solution.
What will be an ideal response?
x1a + x2b = 
or
x1
+ x2 
= 
x1 = 100, x2 = 200
