Question 198209: Suppose you have a lemonade stand, and when you charge $1 per cup of lemonade you sell 50 cups. But when you raise your price to $2 you only sell 25 cups. Write an equation for the number of cups you sell as a function of the price you charge. Denote "C" for number of cups, and "P" for the price you charge. Assume the function is linear.

If I plot price on the vertical axis and # of cups
on the horizontal axis, I have 2 points given:
(50,1) and (25,2)
The formula to use is:

Multiply both sides by

answer
check:
does the line go through (50,1) and (25,2)?

OK
Here's the plot:
