Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2/3x - 1
x = 2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(2) = 2/3(2) - 1
- Multiply: f(2) = 4/3 - 1
- Subtract: f(2) = 1/3
8g + 2 + 4g - 2 - 2g = 10g
Answer:
<h2>
Joe should choose $2100 + 4% of Sales</h2>
Step-by-step explanation:
The options available to Joe are ($1800 + 6.5% of sales) and ($2100 + 4% of sales) for his salary. He chooses the option in which he would get higher salary. Sales are expected to lie between $5000 and $10000.
Let the sales be denoted by 
(in Dollars). Joe chooses first option if it is a higher number than the second.
⇒ if 
So, he chooses first option if 
. However sales is between $5000 and $10000. So, Joe will go with second option.
∴ Joe should choose $2100 + 4% of sales.

Answer:
The maximum profit is 5070 dollars
Step-by-step explanation:
The profit y is represented by a quadratic function.
The equation that we can use to find a maximum value of a quadratic function is:
Max_value = c - (b^2 / 4a)
Where a, b and c are the coefficients of the quadratic function (in our case: a = -13, b = 770, c = -6332)
So, using this equation, we have:
Max_value = -6332 - (770^2 / 4*(-13)) = -6332 - 592900/(-52)
Max_value = -6332 + 11401.92 = 5069.92
rounding to the nearest dollar, we have that the maximum profit is 5070 dollars.
