Question

1. a student scored 72 points on a test, which was 80% of the total possible points. how many fewer points did the student score than the maximum possible points?

Explanation:

Step1: Find total possible points

Let total points be \( x \). Given \( 80\% \) of \( x = 72 \), so \( 0.8x = 72 \). Solve for \( x \): \( x=\frac{72}{0.8}=90 \).

Step2: Calculate the difference

Subtract scored points from total: \( 90 - 72 = 18 \).

Answer:

18
