Answer: 9
Step-by-step explanation: 12*12/16
Yes it is a solution because if you take the equation and plug the point in for the x and y :
4 (2) + 3 (3) < 20
8 + 9 < 20
17 < 20
which is true
10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true
by just addding it and diving
660 divided by 2 and it gives you your answer of 13.2
So therefore the answer is 13.2 per hour
