(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.
