Question

1. Nicole usually scores between 89%

and 100% on her math quizzes,
unless the quiz is the day after a track
meet. On the quizzes she takes right
after a track meet, she has about an
11% decrease in her scores. If Nicole
had a track meet the day before a
quiz, what would she score on the
quiz?
A Between 70% and 78%
B Between 79% and 89%
C Between 90% and 99%
D Between 100% and 111%

Answer 1

The Answer is: B. 79% and 89%

Explanation:

Subtract 11% from 89 and 100 to get the range:

89 - (89*.11) =

89 - 9.79 = 79.21

100 - (100*.11) =

100 - 11 = 89
