Jace is working on a project for school where he needs to find the best overall price for labor and materials. All of the companies he is looking at have approximately the same labor and materials prices, but their material loading percentages are all different. The three percentages are 20%, 32%, and 51%. Which one should Jace choose?

a) 51%, because the material loading percentages should be approximately half of the total cost of materials.

b) 20%, because finding the company with the lowest material loading percentage will result in the lowest total price for labor and materials in this situation.

c) 32%, because 20% is far too low and will negatively impact the total price, but 51% is far too high and will drive the price up.

d) 51%, because finding the company with the highest material loading percentage will result in the lowest total price for labor and materials in this situation.
