sonya's average in math class is an 84 after 3 tests. what must she get on the next test to raise her average to an 88?

If she gets score x, then we have

84*3 + x = 88*4
252+x = 352
x = 100

Good luck, Sonya!

Thank you can you please help me with my other question?

To find out what Sonya must get on the next test to raise her average to 88, we can follow these steps:

Step 1: Determine the total points Sonya has earned so far
Since Sonya has taken 3 tests and has an average of 84, her total points on these three tests is (3 * 84) = 252.

Step 2: Determine the number of tests Sonya has taken
Sonya has taken 3 tests so far.

Step 3: Determine the total points Sonya needs to aim for
To raise her average to 88, Sonya needs to aim for a total of (4 * 88) = 352 points after taking the next test.

Step 4: Determine the points Sonya needs to score on the next test
To determine the points Sonya needs to score on the next test, subtract the points she has earned so far from the total points she needs to aim for: (352 - 252) = 100.

Therefore, Sonya needs to score at least 100 on the next test to raise her average to an 88.
