Joey plans to purchase c pounds of chicken, s pounds of steak, p pounds of potato salad, and m pounds of macaroni salad.
Which equations represent the possible number of pounds he can buy?

A. 1.99c+4.49s=40
1.49p+2.99m-75

B.1.99c+4.49s=75
1.49p+2.99m- 40

C. (1.99 +4.49) (c+s) = 40
(1.49 +2.99) (p+m) = 75

D. (1.99 +4.49) (c+s) - 75
(149+2.99) (p+ m) = 40
