Andrew got a 95% on the test. If there were 80 questions on the test, and every question worth the same, how many questions did
Lemur [1.5K]

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.

80\times \frac{95}{100}=76

The 95% of 80 is 76. So, 76 answers are correct.

Therefore out of 80 Andrew did 76 questions correctly.

PSYCHO15rus [73]

In this equation there are few key numbers, thankfully XD, so it does not take too long to figure out that the 0.04 is clearly a tax on the repairs as 30h is representing the hours spent repairing Kimber's phone.
