Question

a student has had a collection of baseball cards for several years. Suppose that B, the number of cards in the collection, can be described as a function of t, which is time in years since the collection was started.Explain what each of the following equations would tell us about the number of cards in the collection over time. 1. b=200+100t 2. B=100+200t 3. B=2000-100t 4. B=100-200t need help please !

Answer 1

Are we missing a graph?

Answer 2

This about Function Models

Answer 3

the first one...b = 200 + 100r...
indicates that you started with 200 cards (the y-intercept), and then every year you add another 100. And b equals the total amount of cards for the given about of time
(Note: don't know why it is r instead of t)

Answer 4

@TheSmartOne there are no graphs. You are supposed to explain what each function represents in correlation with the scenario given.

Answer 5

Oh that makes sense lol

Answer 6

I know why is it r and not t lol

Answer 7

Just keep going along those lines @cookielate . And remember that "-" instead of "+" indicates a loss of cards instead of gain

And why @TheSmartOne ?

Answer 8

I just stated what you said that why is it r when it says it is t...

Answer 9

You start off with 2000 but each year you will loose or give away 100 cards.
