Answer:
She must score 90 points
Step-by-step explanation:
Find the average of the first 2 tests
76 + 80 = 156
Divide the sum of the first 2 tests by how many tests there were
156 ÷ 2 = 78
Multiply 82 by 3
82 x 3 = 246
Subtract 156 from 246
246 - 156 = 90
Add all the numbers together to get the average
90 + 80 + 76 = 246
246 ÷ 3 = 82
