Step-by-step explanation:
Given that the dollar cost of producing x appliances is

A) Average cost can be obtained by dividing c(x) by units = x
i.e. average cost = 
B) Marginal cost = dC/dx = 
When x=140 marginal cost 
C) We calculate
c(140) = 
c(141) = 
Marginal cost = difference = 33.80
Same as 34 shown in marginal cost.

Step 1
Define the <u>variables</u>
Let
x-----> number of erasers
y-----> total cost
we know that

------> this is the <u>linear equation</u> that represent the situation
therefore
the answer is
