Question

In the last election, candidate b received twice as many votes as candidate

Answer 1

A + b + c = 109,000
b = 2a
c = a - 15,000

a + (2a) + (a - 15,000) = 109,000
4a - 15,000 = 109,000
4a = 109,000 + 15,000
4a = 124,000
a = 124,000/4
a = 31,000

b = 2a
b = 2(31,000)
b = 62,000 <==== candidate b received 62,000 votes

c = a - 15,000
c = 31,000 - 15,000
c = 16,000
