Ms. Mitsuko told the class that if the average score on their quiz is higher than 75% then they will get a pizza party. There are 25 students in the class. One student is absent and has to take the test the next day. The average score of the students who took the test was 77%. What is the lowest grade the absent student can get for the class to still get a pizza party?
How many points does the class need to get? ** The total percentage the class needs to get is 18.75 because 25 x .75 = <<25*.75=18.75>>18.75
How many points does the class have absent the one student? ** The total percentage the class has absent the one student is <<18.48=18.48>>18.48
What is the lowest grade the absent student can get for the class to still get a pizza party? ** The lowest the absent student can get and still have a pizza party is 27% because (18.75-18.48)x 100 = <<(18.75-18.48)*100=27>>27
