Question

You downloaded a video game to your computer. You have a 60-minute free trial of the game. It takes 5.2 minutes to set up the game and 7.3 minutes to play each level. You want to find out how many levels you can play for free.

Answer 1

Solution:

Note that:

• 1 game played = 5.2 + 7.3 minutes
• Trial lasting = 60 minutes

Finding how much levels for free.

• x games = 5.2 + 7.3x = 60 minutes
• => 7.3x = 54.8 minutes
• => x ≈ 7.51

Round it down to find the exact number of free levels you can play.

• => 7 games

We can play 7 levels for free.

Answer 2

Answer:

7 levels

Step-by-step explanation:

Let x = number of levels

⇒ 5.2 + 7.3x = 60

⇒ 7.3x = 60 - 5.2 = 54.8

⇒ x = 54.8 ÷ 7.3 = 7.5068...

Need to round down to whole complete levels, so number of levels you can play for free = 7
