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.

Answer:
-18
Step-by-step explanation:
First you have to know the price of item.
EX: Say a candy car costs $1.50.
The candy bar was marked down 30%.
$1.50 x 30/100 = $.45
The item will decrease $.45.
$1.50 - $.45 = $1.05
1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price
