Question 1210328
<pre>
Indeed, since this problem has only 4 possible ways to buy the uniforms and
social clothes and spend no more than N3600, it can be solved informally.

However, I believe this problem was assigned to lead the student to understand
linear programming problems, which require graphical solutions, for instance,
like this one:

<i><b>A factory manufactures two types of gadgets, regular and premium. Each gadget
requires the use of two operations, assembly and finishing, and there are at
most 12 hours available for each operation. A regular gadget requires 1 hour of
assembly and 2 hours of finishing, while a premium gadget needs 2 hours of
assembly and 1 hour of finishing. Due to other restrictions, the company can
make at most 7 gadgets a day. If a profit of $20 is realized for each regular
gadget and $30 for a premium gadget, how many of each should be manufactured to
maximize profit?</i></b>

This problem requires graphical methods, and no doubt is the sort of problem
this student will very soon be required to solve.  That's why I chose to solve
the given problem as close to the way to solve the above problem as possible.
