Question

17. Last year, 320 students were members of Pine Hill Middle School clubs. This year, there was a 20% increase in memberships. How many students are members this year?

Answer 1

Last year, 320 students were members of Pine Hill Middle School clubs, and with this year's 20% increase in memberships, the new total number of members is 384 students.

Step-by-step explanation:

The question asks us to calculate the number of students who are members of Pine Hill Middle School clubs this year, given a 20% increase from last year's membership of 320 students. A 20% increase means that the number of new members is 20% of 320. To find this number, we calculate 20% of 320:

20% × 320 = 0.20 × 320 = 64

Next, we add these 64 new members to the original number to get the total membership this year:

320 + 64 = 384

Thus, this year the number of students who are members of the clubs is 384.
