Answer:
Out of 80 questions Andrew did 76 questions correctly.
Step-by-step explanation:
Total number of questions is 80.
It is given that he got 95% on the test. It means he answered 95% of the total questions correctly.
First we have to calculate 95% of 80.

The 95% of 80 is 76. So, 76 answers are correct.
Therefore out of 80 Andrew did 76 questions correctly.
Try to start by reading the manual it came with. If it didn't come with a manual, then your teacher in school will teach you how to use it for specific commands. Otherwise it's just like using a regular calculator but with the ability to do more things, what do you need to know on it?
Answer:
