Three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally. write an inequality to find possible amounts each friend earned. identify what your variable represents.

Let the original  amount they earned be x.

They earned more than $200, therefore  x > 200

They paid their parents $28, assuming all the parents got $28

So we remove 28 from both sides of the inequality

x -28> 200-28

Let y be the amount left after paying their parents, and  replace (x -28) with y in the inequality above.

 y> 200-28

y> 172

Amount each got, divide both sides of the inequality by 3.

y/3 > 172/3     

Let amount each got after dividing equally be z, replace (y/3) with z in the inequality above

z > 172/3

z > 57.33

Each got more than $57.33
