The area a painter can paint varies directly with the amount of time he works. One morninig, he painted 204 ft² between 8 a.m. and 12:15 PM. Write a direct variation equation to describe the area y covered in x hours.

The forumlua for direct variation is y=kx

**Reiny**, Wednesday, November 17, 2010 at 8:36pmYour data tells us that if x = 4.25, y = 204

sub into the equation

204 = 4.25kk = 204/4.25 = 48

so y = 48x
