A company sells boxes of small blue pom-poms (b) for $42 and boxes of large orange pom-poms (p) for $52. They make batches of small blue pom-poms that fill 8 boxes and batches of large orange pom-poms that fill 4 boxes. The company only has 40 boxes. Which system of equations helps the company plan to make $350?

(A) b = 40 − p
8b + 4p = 40
(B)b = 40 − p
42b + 52p = 350
(C) 8b = 40 − 4p
42b − 52p = 350
(D) 8b = 40 − 4p
42b + 52p = 350
