Question

edna is playing the video game dragon’s deliveries. when she delivers a package to the wrong dragon, a message says −10 points, and her score decreases by 10 points. if edna loses a package, a message says −20 points. which of these describes what happens to edna’s score when she loses a package? it decreases by 20 points. it stays the same. it increases by 20 points.

Explanation:

Step1: Analyze the problem

The problem states that when Edna loses a package, the message says -20 points. A negative score change means a decrease in score.

Step2: Evaluate the options

• "It decreases by 20 points" matches the -20 points message, as a negative value indicates a decrease.
• "It stays the same" is incorrect because the message indicates a score change.
• "It increases by 20 points" is incorrect because a negative value ( -20) does not represent an increase.

Answer:

It decreases by 20 points.
