Question 363658: This year, 75% of the graduating class had taken at least 8 math courses. Of the remaining class members, 60% had taken 6 or 7 math courses. What percent of the graduating class had taken fewer than 6 math courses? Answer by ewatrrr(24785) (Show Source):
Hi,
75% of the graduating class had taken at least 8 math courses
"Of the remaining class members", 60% had taken 6 or 7 math courses.
60%* 25% = 15% of the graduating class had taken 6 or 7
15% + 75% = 90% had taken 6 or more math courses
10% of the graduating class fewer than 6
