Question

Beth plays a video game in which she starts with 0 points. In round 1, she losses 31/2 points in round 2, she wins 281/2 points ,and in round 3, she losses another 3 1/2 points .What is her final score?

Answer 1

`21(1)/(2) \ or\ 21.5`

Explanation:

Given that:

Initial score of Beth = 0

Round 1 scores:

Points lost =
`3(1)/(2) = 3.5`

Round 2 scores:

Points won =
`28(1)/(2)=28.5`

Round 3 scores:

Points lost =
`3(1)/(2) = 3.5`

To find:

The final score of Beth in the video game = ?

Solution:

Let us calculate the total points lost and total points won by Beth in the video game.

Then we will subtract the total points lost from the total points won to find the final score in the video game.

Total points won = 28.5

Total points lost = 3.5 + 3.5 = 7

So, final score = Total points won - Total points lost

Final score = 28.5 - 7 = 21.5 or
`\bold{21(1)/(2)}`
