Question

Julian is interested in building a new house. Three architects have given him plans. The first plan is for a house that will be 2,250 square feet. The total cost of the house will be $281,250. The second plan is for a house that will be 2,400 square feet. The total cost of the second house will be $288,000. The third plan is for a house that will be 2,500 square feet. The total cost of the third house will be $305,000. If Julian wanted to choose the plan with the least expensive cost per square foot, which would he choose?

A. plan 1

B. plan 2

C. plan 3

D. All of the plans cost the same per square foot.

Answer 1

I would choose Plan 2

Divide the number money by the number of square feet.

Plan 2 is $120 cost per square when you divide 288000÷2400=120.

Thats the least expensive for 1 square ft.
