A manufacturer needs to pay $300 to start making a certain new product. Besides the initial costs of $300, this product will als

maw [93]

Answer:

$\displaystyle \frac{300+18x}{x}\le 24$

Step-by-step explanation:

<u>Average Cost</u>

Making a certain new product costs $300 plus $18 per product.

The total cost for x products is given by:

300 + 18x

To get the average cost, we divide the total cost by the number of products manufactured:

$\displaystyle A=\frac{300+18x}{x}$

If the manufacturer wants to keep the average cost at $24 or less:

$\mathbf{\displaystyle \frac{300+18x}{x}\le 24}$

This is the required inequality

Use the table to work out the values of a, b,

Dvinal [7]

So to find the value of -3 do the following process:

Insert the -3 in the x’s in the equation on the top of the table

y= 5x -3x to the second power + 3

y= 5 (-3) -3(-3) to the second power + 3

Then continue to simplify the equation

y= -15 + 9 to the second power + 3

y= -15 + 84

y = 69

Y= 69 for the chart for -3

For b, c, and d insert the number in the x values and simplify like the previous equation.

If you are confused, feel free to ask questions. I hope this is effective and helps you in your studies.
