The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.

Step-by-step explanation:
We are expected to solve the weighted average price per kilowatt hour.
Step one:
The formula is
W =∑wX/∑w
W=weighted average
w=weights applied to x values
X=data values to be averaged
Step two:
given the total killowatt hour is 1800
the 1st = 500 at 3¢
2nd= 1000 at 2¢
3rd = (1800-1000+500) at 1¢ =(1800-1500) at 1¢ = (300) at 1¢
Step two:
Substituting into the expression we have
W =(500*3)+(1000*2)+(300*1)/500+1000+300
W=1500+2000+300/1800
W=3800/1800
W=2.11¢
The average price per kilowatt hour the utility paid to Mr. Vestas last month is 2.11¢
