Question 174359: Suppose that the credit remaining on a phone card (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function gives a line with a slope of . See the figure below.
There is 29.16 in credit remaining on the card after 32 minutes of calls. How much credit was there after 24 minutes of calls?
Can somebody help me with this? I can't get the right answer and grapg it. TY judy
You can put this solution on YOUR website! You're missing the slope. You wrote: "the function gives a line with a slope of " but forgot to write in the slope. Please repost.
