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.

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

I’m pretty sure the slope would be 1 since the x and y values increase by 1

The answer that i got was 8/3
