Question

bob has 100 collectible baseball cards and is sending 15 per month to his grandson Tom. Meanwhile Tom's friend Peter has started collecting baseball cards as well. He plans to purchase 5 cards per month. Write a system of equations
graph the system
after how many months will they have the same number of cards?

Answer 1

Answer:

5 months

Step-by-step explanation:

        Let:

[]  b be the number of cards Bob  has

[] p be the number of cards Peter has

[] m be every month that passes, "per month," etc

        "Bob has 100 collectible baseball cards and is sending 15 per month to his grandson Tom"

b = 100 - 15m

        "He [Peter] plans to purchase 5 cards per month."

p = 5m

        It asks us to graph the system. The point of intersection is the solution to our problem.
