(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.
Hey, you have not given the charge rate per hour of contract 1 and 2. Unable to solve due to incomplete information.
(a)10700
(b)10875
(c)11100
(d) I think Mrs. Solar should choose contractor should choose contractor 3. beacuse contractor finish the work faster.
Mrs. Solar can eliminate contractor 1,beacuese Contractor 1's time estimate is 210 h which larger than Mrs. Solar expected.
However,the appropriate answer is Mrs. Solar should choose contractor 2 beacuse contractor 2's rate of charge 10875/195 is less than contractor 3's rate of charge 60.
