Gabriel took a math test and scored an 80. He got 4 questions wrong and lost 20 points. How many points were each item?

Each question was worth 5 points.

Step-by-step explanation:

If every question had the same worth, then that would be easier to calculate.

First divide the points he lost by how many questions.

20 ÷ 4 = 5

Now we have it! Each question is worth 5 points!

But if you want to find how many questions in total the test had, we can do that too!

100 ÷ 5 = 24

The test had 24 questions!
