Answer:

a. C = 12x + 110; b. $290

Step-by-step explanation:

a. The polynomial

 Let L = cost of flip-flops

and S = cost of sandals

Then

C =      L      +      S

  = 40 + 4x + 70 + 8x

  = 12x + 110

b. The cost

C = 12 × 15 + 110

  = 180 + 110

  = $290

The cost of making 15 flip-flops and 15 sandals is $290.
