Answer:
144 people were originally at the party.
Step-by-step explanation:
18 boys is one fifth of the second boys population, so the second population is 18x9 = 162. The original population would be 162-18, which equals 144.
1.7-3-2.4y= 12y-11.64
-1.3-2.4y = 12y - 11.64
-2.4y = 12y - 11.64
-14.4y = -10.34
y= 10.34/14.4= 5.17/7.20 or 517/720
