C(x)=125x+75
You multiply 125 by how many family members and and the 75
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.
Solving, we get 40 = 2x, x =20
The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.
Hope this helped!
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
