Question 61428: It is approximately 300 miles from Chicago, Illinois, to St. Louis, Missouri. Allowing for various traffic conditions, a driver can average approximately 60 miles per hour.
a) How far have you traveled after 3 hours?
Answer: 180 miles
Show work in this space: 3(60) = X (I think this is how it has to be done)
b) How far have you traveled after 4 hours?
Answer:4(60)
Show work in this space:
c) How far have you traveled after t hours? i.e. write a linear function that expresses the distance traveled, d, as a function of time, t.
Answer:

Question 64972: I have tried and tried to remember the formulas and have done research to refresh my memory, but it's just not working. Here's the question:
If you charge $1 per cup of a drink and sell 50 cups, then you raise your price to $2 per cup and sell only 25 cups, write an equation for the number of cups that you sell as a function of the price you charge. "C" is for # of cups and "P" is for the price you charge. Assume that the function is linear.
Thank you
This problem is from an assignment from a course through correspondence.
