Question

On last week's quiz, Andre got 18 questions correct and 2 questions incorrect. What was Andre's score

Answer 1

Answer:90%

Step-by-step explanation: we know this because the total about of questions on the test is 20 and for the score to add up to 100% each question has to be worth 5% so we can just do 5 x 18 to get 90%. or (5 x 2) - 100 to also get 90%
