Question

Henry initially has 523 baseball cards. He buys 24 cards each month. What is the explicit rule for the number of baseball cards Henry has in n months?

Answer 1

Hi there!
Basically, we are asked to write a rule that can model the number of baseball cards Henry has in any given month. The variable that we are asked to use is 'n', which represents the number of months. First of all, we are given that Henry initially had 523 baseball cards, and he kept buying 24 baseball cards each month additionally. We can use this formula to model any question like this-

Total Amount = Rate(variable) + Initial Amount

As said before, our initial amount is 523, and our rate is 24. Now, just plug it back in. 
Total Amount = 24n + 523
Therefore, the rule that models the number of baseball cards Henry has in 'n' months is 24n + 523. Hope this helps!

Answer 2

Hello There!

It is 523 + 24n

Hope This Helps You!
Good Luck :)
