(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.

Contractor 1's formula is y=50x+200

Contractor 2's formula is y=150+55x'
