Question 620849: The value, v, in the hundreds of dollars, of Bob's stamp collection is 12 dollars more than 1/3 of the age, t(in years).
Graph the equation and use the graph to determine the value of Bob's collection if it is 9 years old. Answer by math-vortex(648) (Show Source):
You can put this solution on YOUR website! Hi, there--
.
Let v be the value of the stamp collection (in hundreds of dollars)
Let t be the age of the collection (in years)
.
We use the information in the problem to write an equation that models the situation.
.
We want to know the value v when the collection is 9 years old (t=9). Using the equation, we substitute 9 for t and solve for v.
.
.
In the context of this problem, v=15 means that the collection is worth $1,500 (15 hundred dollars).
.
Here is how you would do this on a time vs. value graph (see graph below):
.
The horizontal axis is time t. The vertical axis is value v.
Go across the horizontal axis to 9 (t=9 years).
Now move straight up the graph from that point until you touch the line for the equation.
Look across to see the value on the vertical axis at that point.
You will see that it is v=15.
Remember that in this equation, value is in hundreds of dollars, so 15 means $1,500.
.
I hope that this helps! Feel free to email me again if you still have questions.
