Answer:
12 people
Step-by-step explanation:
This is a problem that involves common ratios. 7 people bought jerseys for every 2 people who bought programs. We need to figure out how many people bought programs if 42 people bought jerseys. If we let the number of people who bought programs be x, we can set up an equation like this:
If we cross multiply, we get the following:
We can solve for x by dividing by 7, and getting that x = 12. This means that 12 people bought programs.

Check for critical points within the unit ball by solving for when the first-order partial derivatives vanish:
Taken together, we find that (0, 0, 0) appears to be the only critical point on
within the ball. At this point, we have 
.
Now let's use the method of Lagrange multipliers to look for critical points on the boundary. We have the Lagrangian
with partial derivatives (set to 0)
We then observe that
So, ignoring the critical point we've already found at (0, 0, 0),
So ultimately, we have 9 critical points - 1 at the origin (0, 0, 0), and 8 at the various combinations of
, at which points we get a value of either of
