Question

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)

Answer 1

wouldn't
T(x) = L(x) + M(x) , that is, the combined cost of labour and material ?

" Need to evaluate the total cost of polynomial for x=500 "

just replace x with 500 and evaluate

" cost of labor for 500 transmissions "
replace x with 500 in L(x) and evaluate

" cost of materials for 500 transmissions. "
replace x with 500 in M(x) and evaluate

Answer 2

Thank you for your help, I really appreciate it.
