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. a. B=200+100t b. B=100+200t c. B=2000–100t d. B=100=200t
1.The students started with 200 cards and each year the card value goes up 100 plus the amount. Y=100t+200
2. The students started with 100 card and each year adds to 200 collections.
3.The students started with 2,000 and and loses 1,000 card each year.
4.students started with 100 cards and give 200 cards away each year.
