You are going to decide how you would prefer to commute to work each day.

Step 1 is to choose a value for p between 50 and 100; this is the initial number of cars on the road.

Step 2 is to choose a value for a; this is the growth factor you can choose a to be any number between 0 and 1 OR choose a to be any number greater than 1.

1) Insert the chosen values for p and a into the formula listed above.

2) Use the formula to find the number of cars, C, on 1st Avenue at any three values of time, t, in days that you want. Show your calculations and put units on your final answer!

3) Provide a written summary of your results explaining them in the context of the original problem. Would you want to commute to work each day on this road? Explain why or why not.

Do NOT use the same values for p and a as another student in the class.

**bobpursley**, Friday, February 19, 2010 at 10:56amThis is "college"? This was a standard assignment for ALG II students in the exponential decay section.

So what is your question? Choose p (I suggest 100), and a. You need at least one value of a <1 (decay), and a couple of values above 1, (growth).

I would graph them also with your graphing calculator.

Please put your subject in the subject box, terms like "college", "adult", are meaningless to our answering volunteers, and is a waste of their time trying to seek out their subject questions.

**jeffery**, Friday, February 19, 2010 at 11:09amSuppose that the number of cars, C, on 1st Avenue in a city over a period of time t, in months, is graphed on a rectangular coordinate system where time is on the horizontal axis. Further suppose that the number of cars driven on 1st Avenue can be modeled by an exponential function, C= p * a t (C=p*a^t) where p is the number of cars on the road on the first day recorded and t is the number of days.

Step 1 is to choose a value for q between 50 and 100; this is the initial number of cars on the road.

Step 2 is to choose a value for z; this is the growth factor you can choose z to be any number between 0 and 1 OR choose z to be any number greater than 1.

1) Insert the chosen values for q and z into the formula listed above.

2) Use the formula to find the number of cars, C, on 1st Avenue at any three values of time, t, in days that you want.

3) Provide a written summary of your results explaining context of the problem. Would you want to commute to work each day on this road?

How to I solve this problem using the number 75 for Q & 2 for Z?

**bobpursley**, Friday, February 19, 2010 at 11:21amThe model given to you was

Cars=OriginalNumber*(growth factor)^{t}

In the steps, Q is the original number

z is the growth factor

t is time in days.

**jeffery**, Friday, February 19, 2010 at 11:25amI'm very confused?
