Suppose your business operates a machine at a cost of $100 per day whether it is used or not plus $50 for each hour it is used. use the line drawing tool to draw the daily cost curve for this machine assuming an 8 hour day. label the curve 'cost'. carefully follow the instructions above, and only draw the required objects.

You can find the drawing in the attached file

Explanation:

You have fixed cost of $100 whter the machine is used or not and a variable cost of $50 for each hour used. So if you do not use de machine the cost will be $100, if the machine is used 1 hour the cost will be $150 and will increase $50 per aditional hour, until it reaches $500 ($100 + 8*50)

The drawing must have two variables, one is cost and the other is hours.

Cost start from $100 when the machine is not used and grows $50 per hour

b. take periodic breaks and alternate between tasks.  

will increase work efficiency, and avoid health issues.
