Question

Lindsay is playing a video game. She begins with an initial score of 300 points but loses 180 points throughout the game. She represents her score using the expression below: 300 - 180. Which expression also represents Lindsay’s video game score?

a) 300 – 180
b) 180 + 300
c) 300 + (-180)
d) 300 + (1280)

Answer 1

Lindsay's video game score after losing points can be represented as '300 - 180' and '300 + (-180)' because adding a negative number is equivalent to subtraction. The correct expressions for her final score are options a) and c).

Step-by-step explanation:

Lindsay is playing a video game where she begins with an initial score of 300 points but loses 180 points throughout the game. She represents her score using the expression below: 300 - 180. Now, let's analyze which expression also represents Lindsay’s video game score.

Option a) 300 - 180 is the initial expression given and correctly shows a loss of 180 points from 300.

Option b) 180 + 300 would suggest Lindsay is adding 300 to 180, which is not representing a loss and hence incorrect.

Option c) 300 + (-180) is the same as subtracting 180 from 300 because adding a negative number is similar to subtraction. Therefore, this expression is also a correct representation of Lindsay’s video game score after losing points.

Option d) 300 + (1280) suggests adding 1280 to 300, which significantly increases her score and does not match the scenario described.

In conclusion, the correct expressions that represent Lindsay’s video game score after losing 180 points are 300 - 180 and 300 + (-180).
