Step-by-step explanation:

Total number of questions in the test is 80.

To receive a grade of A on the 80 question test, 90% of the questions must be answered correctly. It means that the number if questions that must be answered correctly would be

90/100 * 80 = 0.9 * 80 = 72.

Therefore, the maximum number of questions that can't be missed to still receive an A is 72
