Suppose that c (x )equals 7 x cubed minus 70 x squared plus 13 comma 000 x is the cost of manufacturing x items. Find a production level that will minimize the average cost of making x items.

Step-by-step explanation:

Given that

is the cost of manufacturing x items

The average cost per item is

Now  we get

Here x≥0 since it represents the number of items.,

Put x=0 in

For x=0 the average cost becomes 13000

Differentiating f(x) with respect to x

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
