please help me.... A painting company charges $250 base plus $16 per hour. Another painting company charges $210 base plus $18 per hour. How long is a job for which the two companies costs are the same?

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!
