Eighty students took the pre-algebra test and 90% of them scored 85% or higher. How many students scored 85% or higher on their test? How many students scored below 85% on their test?
0.9 * 80 = ?
72 scored higher than 85%
8 scored lower
Anon how did you work the problem?
It looks like Anon solved the problem as I posted it.
To find out how many students scored 85% or higher on their test, we need to calculate 90% of the total number of students who took the test.
First, let's find 90% of 80:
90% * 80 = 0.90 * 80 = 72
Therefore, 72 students scored 85% or higher on their test.
To find out how many students scored below 85% on their test, we can subtract the number of students who scored 85% or higher from the total number of students who took the test.
Total number of students who took the test = 80
Number of students who scored 85% or higher = 72
Number of students who scored below 85% = Total number of students - Number of students who scored 85% or higher
Number of students who scored below 85% = 80 - 72 = 8
Therefore, 8 students scored below 85% on their test.
