Fred got a score of 68 on the test. Enter a division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test
Solution
68 = (1-W/T)100 where W= incorrect answers and T = total problems
68 =100-100W/T
If there were 100 questions, he missed 32
If 200 questions, he missed 64
he missed 32% of the questions assuming each question had the same weight
His grade = 100 times (one minus wrong answers divided by total answers)
