Answer:
Option A (89)
Step-by-step explanation:
Number of 7th graders :
Let x represent the total number of the team.
The expression will then be:
47% of x = 79
47 / 100 * x = 79
47x / 100 = 79
Cross Multiply.
47x = 79 * 100
x = 7900/47
x = 168.08
x = 168 (approximately)
Therefore, it means we have a total of 168 team members.
Numbers of 8th graders:
Total number of team members minus number of 7th graders
8th graders = 168 - 79
8th graders = 89
There are 89 8th graders on the team
