Math - Algebra word problem
posted by Ashley on .
Ace manufacturing has determined that the cost of labor for producing x transmissions is
L(x) = 0.3x2 + 400x + 550 dollars,
While the cost of materials is
M(x) = 0.1x2 + 50x + 800 dollars.
Write a polynomial T(x) that represents the total cost of materials and labor for producing x transmissions.
Evaluate the total cost polynomial for x =500.
Find the cost of labor for 500 transmissions and the cost of materials for 500 transmissions.
Any and all help would be greatly appreciated! I am totally confused.
