Let x= the number of bags of soil
20x(less than or equal to sign) 300

Answer:
9
Step-by-step explanation:
If you want to get $15 profit, You will need to paint 9 faces. You spent $12 on painting supplies so this is the explanation.
$3 x 9 = $27
$-12 + $27 = $15
That way, you earn $15.
Y = 4/3(x) + 1/3
Divide both sides by 3
