Do not solve. Set up the correct equations.
To manufacture an automobile requires
painting, drying, and polishing. Epsilon Motor Company produces three types of cars, the Delta, the Beta, and the Sigma. Each Delta requires 9 hours for painting, 2 hours for drying, and 3 hours for polishing. A Beta requires 33 hours for painting, 8 hours for drying, and 4 hours for polishing, and a Sigma requires 8 hours for painting, 1 hour for drying, and 2 hours for polishing. If the company has 419 hours for painting, 89 hours for drying, and 68 hours for polishing per month, how many of each type of car are produced?
My Work:
Let x = painting
Let y = drying
Let z = polishing
9x + 33y + 8z = 419
2x + 8y + z = 89
3x + 4y + 2z = 68
Correct?
