Answer:
28 members
Explanation:
If there is a decrease of 65% , it means that 100%−65%=35% of the members are left.
So we just need to find 35% of 80.
35100×80=28 members.
The other way is to find the actual decrease, which is:
65100×80=52 members
80−52=28 members remain.

Step-by-step explanation:
3x^2+2xy+y2=2
6x + 2y + 2xy' + 2yy' = 0
x=1 ==> y=-1
6(1) + 2(-1) + 2(1)y' + 2(-1)y' = 0
6 - 2 + 2y' - 2y' = 0
4 = 0
