If one shirt equals to $21.46, and you need to purchase 4 shirts to get the free pair of jeans, you multiply 4 by 21.46 and get 85.84. But if there is 42 customers taking advantage of the special, then you need to multiply 85.84 by 42, and you get 3,605.28.
The information from the first equation gives you the information needed for the second. To solve the first equation you must rearrange the equation to isolate X. In order to do that you can first move the 3 to the other side of the equation by subtracting it from both sides (5x + 3 - 3 = 4 - 3) and then simplify that to (5x = 4 - 3) and further to (5x = 1). Then to move the 5 you must divide both sides by 5 so you get (5x/5 = 1/5) which can be simplified to (x = 1/5)
From this you can use the X value and input it into the second equation
Y = -3(1/5) and then solve for Y.

Let's work on Sections. The top rectangle has an area of 54 (6x9) the base rectangle has an area of 360 ((9+6+9+5)×12) and the bottom rectangle has an area of 54 (9×6) now we add and we get 468. thus the answer is C.
