Answer:
42 Democrats members
12 Republicans members
2 other parties members
Step-by-step explanation:
We know that there are a total number of voters of
- 75 (democrats)+17 (Republicans)+ 4( Other parties)= 96 voters
And we know that the bill has passed with 16 nore votes in favor that against, so let's calculate how many votes in favor of the bill we have:
- 96 Votes = F (votes in Favor)+ A (votes against)
also: F= A+16= A = F-16, so:
- 96= F+A= F+F-16 => F= 56 votes in favor of the bill
Thos 56 votes are the sum of the votes in favor from all the parties:
56 = D (votes in favor of democrats)+R ((votes in favor of Republicans)+OTH (votes in favor of other parties)
=> 56= D+R+OTH (A)
also democrat's votes in favor are three times the sum of non-democrat's votes in favor:
- D= 3*( R+OTH) => OTH= D/3-R
and we have 30 more democrats thar republicans voting in favor:
if we replace in the (A) formula:
56 = D+R+OTH => 56= D+D-30+D/3-D+30 =>
- 56=4/3*D => D=42 (DEMOCRATS VOTES IN FAVOR)
- R= D-30 => R= 12 (REPUBLICAN VOTES IN FAVOR)
- OTH= D/3-R= 14-12= 2 (OTHER PARTIE'S VOTES IN FAVOR)
Alright, lets get started.
Jen picked three fourth in half an hour.
Half an hour means 30 minutes.
At the same rate, how many she can pick in 2 hours.
2 hours means 
minutes
Now,
In 30minutes, Jen can pick = 
In 1 minute, Jen can pick = 
In 120 minutes, Jen can pick = 
Hence Jen can pick complete 3 in 2 hours of time.
So the answer is 3 : Answer
Hope it will help :)
