Chris has a collection of 20 baseball cards and Kyle has collection of 40 baseball cards. Chris is adding 3 baseball cards per m
UkoKoshka [18]

Answer:

11 months

Step-by-step explanation:

The initial number of baseball cards that Chris has is 20.

This is like the first term of a sequence.


If Chris is adding 3 baseball cards per month, then there will be a constant difference of 3.

The number of baseball cards after n months is given by the formula;

C_n=20+(n-1)3


\Rightarrow C_n=20+3n-3


\Rightarrow C_n=3n+17 where n\ge1


Similarly, Kyle initially has 40 baseball cards and adds one base ball card per month to  his collection;

The number of his baseball cards after n months is given by the formula;


K_n=40+(n-1)1


K_n=40+n-1


\Rightarrow K_n=n+39


To determine the number of months that will pass before Kyle and Chris have the same number of base ball cards, we equate both equations to get;






\Rightarrow 3n+17=n+39


We group like terms to get;

3n-n=39-17


\Rightarrow 2n=22


\Rightarrow n=11


Therefore Chris and Kyle will have the same number of baseball cards after 11 months.
