Step-by-step explanation:
Given: Expression for Revenue = 
Expression for Cost = 
If profit is the difference between the revenue and the cost then the expression for profit will be:
Profit = Revenue - cost
![=5x^2 + 2x - 80-(5x^2- x + 100)\\\\=5x^2 + 2x - 80-5x^2+x-100\ \ [\text{Multiply ' - ' sign inside the bracket}]\\\\=2x+x-80-100\\\\=3x-180](https://tex.z-dn.net/?f=%3D5x%5E2%20%2B%202x%20-%2080-%285x%5E2-%20x%20%2B%20100%29%5C%5C%5C%5C%3D5x%5E2%20%2B%202x%20-%2080-5x%5E2%2Bx-100%5C%20%5C%20%5B%5Ctext%7BMultiply%20%27%20-%20%27%20sign%20inside%20the%20bracket%7D%5D%5C%5C%5C%5C%3D2x%2Bx-80-100%5C%5C%5C%5C%3D3x-180)
Hence, the expression represents the profit is 3x-180 .

Hope this helped :)
The computation shows that the change in points is 89 3/4 points.
<h3>How to compute the value?</h3>
From the information, at the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day and at the end the stock market goes up 120 1/2 points.
Therefore, the change will be:
= 120 1/2 - 30 3/4
= 89 3/4
