Which of the following points lie in the solution set to the following system of inequalities?

y > −3x + 3
y > x + 2

(2, −5)
(−2, 5)
(2, 5)
(−2, −5)

The best way is to check all answers. lets check answer A first. 
Take the equation y > -3x +3 and substitute 2 for x and -5 for y.
(-5)> -3(2) + 3 
-5 > -6 + 3 
-5 > -3 
we know this is not true so A is not the answer. because it is an invalid solution. 
Lets check B 
(-2)>-3(5) + 3 
-2 > -15 +3 
-2 > -12 
we know this is true so it is a valid solution Now we have to check the other equation with the same point. 
y> x +2 
5> (-2)+2 
5> 0 
we know this is true so its a valid solution.
This means B the correct answer. 

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
