Question

The cost of a new house can be represented by the regression equation c = 120f + 90,000, where $120 is the cost per square foot and $90,000 is the cost of the lot. A new house on a lot costs $438,000. How many square feet does it have?

Answer 1

3650 square feet. 438,000 divided by 120 is 3650.

each square foot is $120.
If the total cost is $438,000, then you have to divide by $120.

Hope it helps

Answer 2

2900 square feet

Step by Step explanation:

you have to subtract 90,000 from the 438,000 then divide by 120 to find f.
