**cost
Could someone break this down Barney style for me?
The manager of a frozen Air Referigerator factory notices that on Monday it costs the company a total of $25,000 to build 30 referigerators and on Tuesday ot cost $30,000 to build 40 referigerators.
(a) Find a linear cost function based on this information
when I think linear cost function i want to put it in this form c(x) = marginal cost(x) + Fixed cost soo.. do I multiply 25000*30=750,000 then... 30,000*40=1,200,000 then i get stuck!
(b) What is the daily fixed cost?
