<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
5x - 7 > 4x + 8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: x - 7 > 8
- Add 7 on both sides: x > 15
Here we see that any value <em>x</em> that is greater than 15 would work as a solution to this inequality.

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

When a point lies on the x-axis, y = 0, the coordinates are ( x , 0 ).
When a point lies on the y-axis, x = 0, the coordinates are ( 0, y ).
