Answer: 83

Step-by-step explanation:

Since the student want to have a mean of 83 in the 7 tests, the total score of the tests will be:

= 83 × 7

= 581

Then, we add the value of the 6 tests and this will be:

= 88 + 73 + 81 + 83 + 79 + 94

= 498

We will now subtract 498 from 581 and this will be:

= 581 - 498

= 83

He needs to score 83 in the 7th test
