<PRE><B>Question 422361</B>
Write the equation for this situation: the value, v, in hundreds of dollars, of Bob’s stamp collection is 12 dollars more than 1/3 of the age, t (in years). 
Then graph the equation and use the graph to determine the value of Debbie’s coin collection if it is 9 years old. 
Please show all of your work.

Value of Bob&#39;s = (1/3)t+12 in hundreds of dollars

How did Debbie get into this problem?
