Question

* George scored on average of 80% of three tests.
What scored must he get on the burth tests to
bring his average to 85%​

Answer 1

Answer:   100%

Step-by-step explanation:

100 + 80 + 80+ 80 = 340  (total scores of 4 tests)

340 divided by the number of tests 4 = 85

George would need to score 100% on his next test to bring his test average from 80 to 85.
