Aziraphale bought books to be shipped to his library, in case they got out of stock. He bought 36 books, each having a total of $10 dollars. The company that supplies him books gave Aziraphale a buy 6, get 60% off sale. How much money did he spend?

216

Step-by-step explanation:

36 times 10 = 360

360 times 0.60  = 216

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
