S(x) = 2x^2 + 14x - 9
U(x) = 12x - 3
Total = S(x) + U(x) = (2x^2 + 14x - 9) + (12x - 3) = 2x^2 + 26x - 12
Answer: 2x^2 + 26x - 12
This shouldn't really be considered an essay question, but whatever.
This is a really awful word problem. They didn't even bother telling us what 'x' is. All you have to do is add the two polynomials, since they each represent a part of the total cost.
(2x^2 + 14x - 9) + (12x - 3)
2x^2 + 14x - 9 + 12x - 3
2x^2 + 14x + 12x - 9 - 3
2x^2 + (14 + 12)x - (9 + 3)
2x^2 + 36x - 12
