Question

On a test, wrong answers are worth -5.25 points and right answers are worth 3.5 points. So far, Marshall has one right answer and one wrong answer. What is Marshall's current score? A number line shows that Marshall's current score is -1.75. Write an addition equation to represent this situation.

Answer 1

Answer:

-5.25 + 3.5 = -1.75

Step-by-step explanation:

This can technically be done two ways. The first is the most simplified, and the second less simplified, and less likely to get the best grade.

1.So long as you don't have to order it chronologically, you should be good with this one: $-5.25+3.5=-1.75$

2.This one IS chronological (she got a correct answer, then a wrong answer), but you can NOT simplify it, because it asks for an addition equation: $3.5+(-5.25)=-1.75$

The best option is probably #1
