Ace manufacturing has determined that the cost of labor for producing x transmissions is 0.3x2+400x+550 dollars, while the cost of materials is 0.1x2+50x+800 dollars.
Find the total cost of producing x=500 transmissions.
Just substitute 500 for x and solve.
(.3x^2 + 400x + 550) + (.1x^2 + 50x + 800) = ?
x^2 = x squared online
