A linear cost function is
C(x) = 7x+ 800. (Assume C is measured in dollars.)
(a) What are the slope and the C-intercept?
(b) What is the marginal cost
MC??
MC =
What does the marginal cost mean?
If production is increased by this many units, the costdecreases by $1.Each additional unit produced reduces the cost bythis much (in dollars). If production isincreased by this many units, the cost increases by $1.Eachadditional unit produced costs this much (in dollars).
(c) What are the fixed costs?
$
(d) How are your answers to parts (a), (b), and (c) related?
slope = fixed costs, and C-intercept = marginal cost
= marginal cost
= marginal costslope = marginal cost, and C-intercept =fixed costs
(e) What is the cost of producing one more item if 50 arecurrently being produced?

What is the cost of producing one more item if 100 arecurrently being produced?
