Question 81319
Let x=# of items and y=cost to produce

We essentially have 2 points (100,10000) and (300,22000) that we need to find the equation of a line that goes through those points


*[invoke calculating_slope 100, 10000, 300, 22000]


So the equation in terms of C and x is (just replace y with C)


{{{C=60x+4000}}}
