Question

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

Answer 1

Let
R--------------------> money earned washing cars by the three friends

1)R>$200--------------> initial inequality

2) they paid their parents $28
R-28>($200-$28)
R1=R-28
R1>($200-$28)------------> R1>$172
R1---------> money earned minus $28

3) divided the rest of money equally
(R-28)/3>$172/3
R3=(R-28)/3-----------> amount each friend earned
R3>$172/3--------------> R3>$57.33 (final inequality)

the answer is
R3>$57.33
