There were 20 girls and 10 boys on the swim team last summer. This summer, the number of girls decreased by 30% and the number of boys increased by 40. How many members are on the swim team this summer?​

Answers

14 girls and 14 boys

Step-by-step explanation:

20 * .30 = 6, 20 - 6 = 14

10 * .40 = 4, 10 + 4 = 14

20Members

Step-by-step explanation:

20-(30%*20)=6

20-6=14

10-(40%*10)=4

10-4=6

6+14=20

28

Step-by-step explanation:

28

Step-by-step explanation:

I am assuming that "voice" is boys. So there were 20 girls and 10 boys. The number of girls decreased by 30%, so the amount of girls now is 70% of the old amount, so there are 7/10 * 20 girls now = 14 girls. The number of boys increased by 40%, so the number of boys now is 14/10 the original number of boys, so there are 14 boys now. 14+14=28 members on the swimming team
