a 500+.04x The 500 is what they always get no matter what and the .04 is the amount they get for each sale which is represented by x b 720=500+.04x Then you let your equation equal the amount you want to make and solve for x by subtracting 500 and dividng by .04

you go 720=500+.04x
anonymous

oh ok and u isolate x right
anonymous
  • anonymous
then 220=.04x
anonymous

yep
anonymous

220/.04=5550
anonymous
