Question

Paul and Karina both collect old Nintendo video games. Paul has 72 video games so far and is collecting four each month. Karina has 120 video games so far and is collecting two each month. After how many months will Paul and Karina have the same number of video games? How many video games will each have?

Answer 1

• Answer:

24 months

168 games

• Explanation:

72 + 4m = 120 + 2m

4m - 2m = 120 - 72

2m = 48

m = 48 : 2

m = 24 months

• After how many months will Paul and Karina have the same number of video games ?

24 months

• How many video games will each have ?

72 + 4×24 = 72 + 96 = 168 games

120 + 2×24 = 120 + 48 = 168 games
