Question:
To find the average, take the sum of the test scores and divide it by the number of students who took the test.
First find the sum of the test scores.
7×93 + 9×96 + 3×70 = 651 + 864 + 210 = 1,725
Next, find the total number of students who took the test.
7 + 9 + 3 = 19
Divide the sum of the test scores by the number of students to find the average.
1,725 \u00F7 19 = ~90.79
