Set up a ratio of either hours per dollar earned or vice versa, it doesn't matter. As long as you are consistent, you can't do it wrong!

Let x = amount earned in 8 hours.
5%2F53.25+=+8%2Fx

a%2Fb=c%2Fd means that ad=bc

5%2F53.25+=+8%2Fx means that 5x+=+8%2A%2853.25%29+

To find x, divide both sides by 5:
x=+%288%2A53.25%29%2F5= $85.20
