A manufacturing company has determined that the cost of labor for producing x transmissions is:
L(x) = 0.3x^2 + 400x + 550 dollars,
while the cost of materials is
M(x) = 0.1x^2 + 50x + 800 dollars.
Need to write a polynomial T(x) that represents the total cost of materials and labor for producing x transmissions.
Need to evaluate the total cost of polynomial for x=500
Need to find the cost of labor for 500 transmissions and the cost of materials for 500 transmissions.
(Any help would greatly be appreciated. I really don't understand any of this)
