We are given two unknown variables P and U packages.
We can see that Leslie has to unpack P packages at work
However, after she had unpacked U number, she stopped.
To first subtract U from P because we were told that U number had been unpacked from P packages which was supposed to be unpacked.
This can be represented mathematically as <em>P-U</em>
Next, we would have to find the percentage of packages <em>not yet unpacked </em>and this would be:
<h3>Unknown Variable</h3>
This refers to an undefined variable which has not yet been disclosed and <em>remain unknown</em> until a value is given to them.

Question:
A small tie shop finds that at a sales level of x ties per day its marginal profit is MP(x )dollars per tie, where
MP(x) =1.85 + 0.12x - 0.0024x². Also, the shop will lose $65 per day at a sales level of x= 0. Find the profit from operating the shop at a sales level of x ties per day.
Answer:
P(x) = 1.85x + 0.06x^2 - 0.0008x^3 - 65
Step-by-step explanation:
MP(x) = 1.85 + 0.12(x) - 0.0024(x^2)
At sales level, x=0, loss = $65
P(0) = - $65
Integrating MP(x) with respect to x
P(x) = ∫MP(x) dx = ∫ 1.85 + 0.12(x) - 0.0024(x^2)
P(x) = 1.85x + 0.06x^2 - 0.0008x^3 + C
Therefore :
P(x) = 1.85x + 0.06x^2 - 0.0008x^3 - 65
