The total cost of building a new home if the builder charges $300 per square foot.

Answer 1

The scenario that can be modeled by a linear function is:

**The total cost of building a new home if the builder charges $300 per square foot.**

This is because the total cost will increase linearly with the number of square feet, resulting in a straight line when graphed. Each additional square foot adds a constant amount ($300) to the total cost, which is characteristic of a linear function.
