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 the cost by the square footage.

Example:
281,250 / 2250 = $125 per square foot

Plan number 2 is cheapest 120

To determine the plan with the least expensive cost per square foot, we need to calculate the cost per square foot for each plan. We can do this by dividing the total cost of each house by its respective square footage.

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

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

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

Therefore, Julian would choose the second plan, as it has the least expensive cost per square foot at $120 per square foot.
