three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally
Flura [38]
28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86  now we gonna find the value of x.
 28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x. 
28x≤114 divide 28 both of side to get value of x so it will be x≤4
