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.

3.14×8.5²×6/3=453.73
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.
