Anestetic [448]
The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)

A local food truck specializes in gourmet grilled cheese sandwiches. Each month, the owners of the truck have a constant total o
Serggg [28]

Answer:

A. (9 - 2.25)s ≥ 5,400

B. They will have to sell more than 800 sandwiches per month. I first started by solving the parentheses which is 6.75. Then I divided 5,400 by 6.75 to get 800.

C. It will now end up looking like this: (8 - 2.25)s ≥ 5,400. Then it will be 5.75. Then divide 5,400 by 5.75. Then you end up with 939.13. You have to round up when you are talking about inequalities with money so it will be 940. So they will have to sell 140 more sandwiches during that month.
