A hockey fan collects hockey pucks used in professional games. She has 12 pucks already in her collection. She has a friend that works at the stadium tha can get her 3 new pucks each month. How many months will it take for her collection to have 18 pucks answer key?

it will take 6 months for her collection to have 18 pucks.

Step-by-step explanation:

Let x represent the number of months it will take for her collection to have 18 pucks.

She has 12 pucks already in her collection. She has a friend that works at the stadium that can get her 3 new pucks each month. This means that the number of pucks that she would have after x months is expressed as

12 + 3x

For her to get 18 pucks, the expression would be

12 + 3x = 18

3x = 18 - 12

3x = 6

x = 6/3

x = 2
