Finally, Mrs. Solar receives the time estimates from each contractor. She wants to have the work done within 5 wk (200 work-hours) of when the work is started, and the sooner the better. She also wants to get a good deal.

(a) Contractor 1's time estimate: 210 h

What is Contractor 1's total cost?

(b) Contractor 2's time estimate: 195 h

What is Contractor 2's total cost?

(c) Contractor 3's time estimate: 185 h

What is Contractor 3's total cost?

(d) Which contractor should Mrs. Solar choose?

Explain your reasoning.
