Question 970467: The following is a guideline, make the situation your own: Real Life Situation- Plumber charges a flat rate of $60.00 and $40.00 for each additional hour. Function is y = 40x + 60
State the function, real life situation, and define your variables (1 point)
Input/Output table with 8 values (2 points)
Graph of the function with clearly labeled x- and y-axes. (2 points)
Find the domain and range (2 points)
Conclusion (1 points)
Answer by KMST(5328)   (Show Source):
You can put this solution on YOUR website! This is the kind of problem where the expected response depends on the student's real world experiences and interests. I know nothing about your real world experiences and interests, and your teacher probably knows you much better. Since my interests and experience are not the same as yours, my answer may clearly show the teacher that someone else solved the problem for you. I will try to use a very bland, generic situation, that I hope is somewhat familiar to you, so I do not show my hand.
Function: 
Real life situation:
Sam has been going to the local summer camp for many summers.
Being 14, Sam can get a job as a junior camp counselor this summer, for $8 an hour.
Returning camp counselors get a $0.50 raise for the next year, on account of their previous year experience.
That could be a good job for Sam this year, and for the next few summers.
Variables:  = years (summers) of experience as a summer camp counselor.
 = hourly pay, in $.
Table:
Graph:
 or maybe 
Domain and range:
This is not a continuous function, because fractional years of experience do not count.
The same happens with the plumber: he/she may charge for  or  hours if the work took 1 hour and 3 minutes,
but the number of hours will not be  for  minutes = 1 hour and 3 minutes,
and the number of hours may always be rounded to a whole number.
Domain: {0,1,2,3,4,5,6,7,8}
Range: {8,8.5,9,9.5,10,10.5,11,11.5,12}
Conclusion:
(I really do not know what they expect for this part)
After this first summer job, Sam may decide to keep working for 8 more summers at the same camp, while going to high school and college, or technical school, and/or some apprenticeship.
After that, Sam will surely have a more grown-up, permanent, whole-year job, hopefully with better hourly pay.
Sam's pay for the camp counselor job will increase linearly with years of experience.
NOTE: If there is some real life situation that resonates better with you, let me know via a Thank You" on this website, and I may help you construct some more meaningful solution to a more meaningful problem.
