Answer:

94

Explanation:

Average = Total / Number of Data


70 * 4 = 280

You have a total of 280 points after 4 quizzes.

4+4=8 quizzes in total

Total you need for average to be 82


82 * 8 = 656

Number of points you need to hit required:


656 - 280 = 376

You need 376 points in total for the next 4 quizzes.


376 / 4 = 94

You need an average of 94 points on the next 4 quizzes.
