Out of all of the games on his phone, 59 were free. How many of the free apps on Andrew’s phone that aren’t games, require internet access?

Answer 1

Out of 150 total apps, Andrew has 39 free apps on his phone that aren't games and require internet access.

Step-by-step explanation:

We are given the following details about Andrew's apps on his phone:

• Total number of apps: 150
• Number of free apps: 98
• Number of apps requiring internet: 78
• Number of games: 108
• Number of games requiring internet: 52
• Number of free games: 59
• Free games requiring internet: 42

We need to find out how many free apps on Andrew's phone that aren't games require internet access.

First, let's calculate the number of apps that are not games:

Non-games = Total apps - Number of games

Non-games = 150 - 108 = 42

Now, let's find out how many non-game apps were free:

Free non-games = Total free apps - Free games

Free non-games = 98 - 59 = 39

Then, we calculate the number of apps requiring internet that are not games:

Internet non-games = Total internet apps - Internet games

Internet non-games = 78 - 52 = 26

Since every app that is not a game and was not free requires internet, then all the non-game apps that are free also require internet. Thus, the number of free non-game apps requiring internet equals the number of free non-game apps:

Free non-game apps requiring internet = Free non-games = 39
