In order to get an A in science, Jack must get at least a 92% on his next test. If test has 30 questions, what is the minimum number he must correctly answer?

Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92

Answer is 28 minimum correct answers to score a 92%.
