Rule: Any positive number is always larger than any negative number.
For example, 10 is larger than -2. So we write 10 > -2.
The same goes for 8 & 1/4 vs -8 & 1/4. It doesn't matter if we involve fractions or decimals.
Visually, positive numbers are to the right of 0 on the number line. Negative numbers are to the left of 0.
Stuff on the right is larger than stuff on the left.

The equation described above can also be written as,
y = -x² + 100x + 4000
To get the number of notebooks that will give them the maximum profit, we derive the equation and equate to zero.
dy/dx = -2x + 100 = 0
The value of x from the equation is 50. Then, we substitute 50 to the original equation to get the profit.
y = -(50^2) + 100(50) + 4000 = 6500
Thus, the maximum profit that the company makes is $6,500/day.
