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.

Answer:
q = -13.2
Step-by-step explanation:
9.7q = 9.1q - 7.92
Subtract 9.1q from both sides.
0.6q = -7.92
Divide both sides by 0.6
q = -13.2
Double check your work.
9.7(-13.2) = 9.1(-13.2) - 7.92
-128.04 = -120.12 - 7.92
-128.04 = -128.04
