Question

Celia played sevarl rounds in a video game. She finished with -60 points because she lost 5 points in each round. How many rounds did she play?

Answer 1

If Celia played several rounds of a video game, the points she scores can be calculated by finding the product of the number of rounds she played and the point she scored per round.

If she scores x points and she plays r number of rounds, her total points, T, can be calculated to be:

`T=x* r`

From the question, Celia scores -60 points. She lost 5 points per round. This means that we have the following parameters from the question:

`\begin{gathered} T=-60 \\ x=-5\text{ (because she loses 5 points)} \end{gathered}`

Therefore, if we put these values into our formula, we can therefore solve for the number of rounds as shown below:

`\begin{gathered} -60=-5* r \\ \text{Dividing both sides by -5, we have:} \\ r=(-60)/(-5) \\ r=12 \end{gathered}`

The number of rounds Celia played is 12 rounds.
