Last week Betsy made 80 on her quiz. This week she made 76. What is the percent of decrease in her score?

From the information given, she made an 80 the first week she took the quiz, then the next week she made a 76. Furthermore, we are asked to find the percent decrease.

Decrease means less. And less means subtraction in terms of Mathematics. So, hence, subtract 76 from 80 to find the percent decrease.

80 - 76 = 4

Now, just add the percentage behind the result.

4%

Therefore, the percent decrease in Besty's score is 4%.
