david must correctly answer 80% of the questions to advance to advance to the next level in her online course david has already answered 26 question and incorrectly answered 4 questions how many of the 15 questoons remaining must david correctlt answer to advance to the next level
Well, 80% of 45 is 28 and since she already answered 26 questions right, she would need to answer 2 more correctly. Â I'm not 100% sure about this because I am not good at math but I believe this is the answer!
