Question

When Sarah finished the next level of her video game, she gained 10

points for each of the four targets she hit and lost 105 points for
taking too long. Write the total change to her score as an integer.

Answer 1

If Sarah received 10 points for each of the four targets she hit, her total point gain from hitting targets would be:

4 targets x 10 points = 40 points

If Sarah loses 105 points for taking too long, her total loss is -105 points (due to the negative change in her score).

As a result, the total change in Sarah's score may be determined by adding her point gain from hitting targets to her point loss from taking too long:

Total difference = 40 points minus 105 points

-65 points total change

As a result, Sarah's score dropped by 65 points after completing the following level of her video game.
