A following construction worker is trying to estimate the cost function for painting jobs. He has the following information:

House Square feet(x) Cost(Y)

1 2,600 $3,300

2 4,100 5,700

3 2,800 3100

4 2850 3150

5 4200 4700

6 2700 3250

7 2375 2800

8 2450 2600

9 2200 2700

10 3700 4100

Using the high-low method, calculate the variable cost per square foot and fixed cost.
