There are 20 girls and 10 boys on the swim team last summer. This summer, the number of girls secreased by 30% and the number of boys ny 40%. How many members are on the swim team thissummer

40 members

Step-by-step explanation:

If such a count is increased by 30%, the increase is found by multiplying such count by 0.30. The new count is found by multiplying the original count by 1.30.

Thus, the number of girls becomes 1.30 (20 girls), or 26 girls, and the number of boys becomes 1.40 (10 boys), or 14 boys.

Thus, the swim team has (26 + 14), or 40, members.
