Answer:
She should buy a total of 25, so one more can

has critical points wherever the partial derivatives vanish:


Then

- If
, then
; critical point at (0, 0) - If
, then
; critical point at (1, 1) - If
, then
; critical point at (-1, -1)
has Hessian matrix

with determinant

- At (0, 0), the Hessian determinant is -16, which indicates a saddle point.
- At (1, 1), the determinant is 128, and
, which indicates a local minimum. - At (-1, -1), the determinant is again 128, and
, which indicates another local minimum.
Answer:
50 boxes
Step-by-step explanation:
first we can find how many apples there are
42*12=504
then subtract 4 of the rotten apples
504-4=500
then find how many boxes there can be
500/10=50
