Answer: 29.3
Step-by-step explanation:
Abby's average after taking 31 quizzes is 76.
Total test scores= 31 × 76 = 2356
After Abby's teacher drops her 3 lowest test scores, her average increases to 81. This means that (31-3)= 28 test scores were used.
Total scores = 28 × 81 = 2268
Sum of Abby's three lowest score
= 2356 - 2268
= 88
Average of the three scores will now be 88 divided by 3
= 88/3
= 29.3
The average is 29.3
