Acompany 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 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
