x = 27500

Answer 2

Answer 3

$22,765,900

Answer 4

if you'll hang on, I'll double-check

Answer 5

absolutely! you rock!

Answer 6

2800 per day and
606$ per x box

Answer 7

It's actually a trick Q, I think.
Min cost at 0, total cost $0.

Answer 8

Because my answer above should have been x=-27500 with a "neg cost," namely -$22,765,900.

Answer 9

But the question says "min average cost," so again, hang on (ugh) ...

Answer 10

expression for the average cost becomes c(x)/x

Answer 11

actually lucifer did get it right!

Answer 12

Average cost is C(x)/x,
so we want to minimize 78400/x + 550 + .01x.

Answer 13

And, yup, I agree, 2800 and $606. Yay, lucifur.
