James and Vanessa were absent for the day of a test. When they returned and took the test, their scores lowered the average score for the entire class by exactly two points, from 82 to 80. If sixteen students took the test on the original test day, what was James and Vanessa�s average test score?

Since 16 students took the test on the original day, and since the average score was 82, then the total score for the test was 1,312 (16 * 82)

Since 2 students (James & Vanessa) were added to the original 16 students to make the average score 80, then the total score, for 18 students was 1,440 (18 * 80)
