Question 990685
For these problems, x will represent the number of items and y will represent the money.

The fixed costs for a certain item are $100 per week. The cost to produce each item is $3 per item.

Using this information, what is the cost equation? Give your answer in slope-intercept form: 
y= 
3X+100
 Preview   

The retailer intends to sell each item for $10/item.

Using this information, what is the revenue equation? Give your answer in slope-intercept form: 
y= 
10X
 Preview   

If in this week 9 items are made, and all items are sold in the week, what are the total costs to the retailer? 
Cost = $
127


What is the revenue from selling 9 items? 
Revenue = $
90


Finally, what is the profit for this retailer? (This is the part i can't figure out)
Profit = $  <---- ?
217.00 (Wrong) Why? How?
<pre>Profit = Revenue - Cost, not Revenue, plus cost, as you have it.
Therefore, the retailer incurred a loss of $37 ($90 - 127, or - $37), as the cost ($127) to make 
the 9 items was greater than the revenue ($90) derived from the sale of the 9 items. Get it?
