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?

Divide each cost by the respective number of square feet and compare.

Julian would choose 'Plan B'.

To determine which plan has the least expensive cost per square foot, you need to calculate the cost per square foot for each plan. This can be done by dividing the total cost of each house by the square footage of that house.

Let's calculate the cost per square foot for each plan:

For the first plan:
Cost per square foot = Total cost / Square footage
Cost per square foot = $281,250 / 2,250 square feet
Cost per square foot = $125 per square foot

For the second plan:
Cost per square foot = Total cost / Square footage
Cost per square foot = $288,000 / 2,400 square feet
Cost per square foot = $120 per square foot

For the third plan:
Cost per square foot = Total cost / Square footage
Cost per square foot = $305,000 / 2,500 square feet
Cost per square foot = $122 per square foot

Based on these calculations, the second plan has the least expensive cost per square foot at $120 per square foot. Therefore, Julian should choose the second plan if he wants to minimize the cost per square foot.
