Problema Solution
At nelia's family runion 4/5 of the people are 18 years of age or older. Half of the people remaining people are under 12 years old. If 20 kids are under 12 years old how many people attended the reunion.
Answer provided by our tutors
let 'x' be the total number of people attending the reunion
4/5 are 18 years of age or older: (4/5)x
half of the people remaining people are under 12 years old: (1/2)(x - (4/5)x) = x/10
20 kids are under 12 years thus
x/10 = 20 multiply both sides by 10
x = 20*10
x = 200 people
200 people attended the reunion.
