- Man that was a great Burger.
- Yeah it was, here comes the waitress with our check.
- How are we going to split $60 between 4 people?
- Jerry's Diner4 burgers $434 soft drinks$10sales tax $7total:$60
- Well let's set up an equation
- the equation would be 4p-7=52
- 4p-7=53 +7 +74p=60
- yes, so the first thing you do is add 7 to both sides like this...
- Now our equation is 4p=60
- 4p-7=53 +7 +74p=60/4 /4p=15
- Right, so the next thing you do is divide both sides by 4 like this...
- So we all have to pay $15 for our burger.
