Answer 2

Gabriela's new average would be

Explanation:

First, if her average on three tests is 85, and she receives 100 on her last two tests, the first step would be to add 85, 100, and 100; Her previous average and the grades she would receive on her last two tests.

85+100+100=285.

The next step would be to count how many numbers we added to receive our sum. We added three. Because of this, we have to divide the sum by three to get Gabriela's average.

285÷3=95.

Therefore, Gabriela's new average would be 95.
