Let C=85x +10

Question

A. create a problem (real world situation) that would lead to this algebraic rule

B. identify the input and the output variables

C. Write a verbal rule for this equation, using your situation from part a

D. Create a input/output table of values corresponding to the following C-values:3,4,5,6, and 7

E. Are the above values reasonable in terms of the context you provided in part a? Explain why or why not

Answer 1

Cost of production = VC + FC = Variable Cost + Fixed Cost = 85x + 10

C(x) = $85 per unit of input + $10 fixed cost

C(x) = 85x+10, x = input, C = output

C(3) = 265

C(4) = 350

C(5) = 435

C(6) = 520

C(7) = 605
