The table shows the value of a coin over several years, with a question mark for a missing value. Use the table to solve a problem involving function models. Which is most likely the value of the coin in 2005? $3.45 $3.55 $3.65 $3.70

OpenStudy (phi):

I would find the change in value divided by change in year i.e. the points all lie on a line, so you can predict the missing value

3.65

C?

OpenStudy (phi):

the year goes up by 5 the amount goes up by 0.30 so I would add 0.30 to 3.35 (price in 2000) to find the price in 2005

You don't seem to know how this works. 1) Post your ENTIRE problem statement from the beginning. You posted nothing at first. This is no good. 2) Show YOUR WORK from the beginning. When you posted your problem statement, no work of your own was shown. 3) Don't contact individual people to help. All are volunteers and they are only around when they can be. 4) Just post your problem statement and show your work and you will get the fastest and best help that can be offered on a volunteer basis. 5) Don't just guess at answers to helpers' questions. Show your work. Conduct a useful conversation. All will be well.

I didn't guess an answer I saw that it went up 30 so thats how i got 3.65. I said C? because i was trying to see if that what you all got. I hate bothering people
