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)
