Millie will have to pay the $20 back, and as she already has no money, she's now $20 in debt
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
Integers that are not whole numbers are like -5 -8 -7 and etc...
1.) % only coffee = 55 - (15 - 5) - (25 - 5) - 5 = 55 - 10 - 20 - 5 = 20%
2.) % only soda = 45 - (25 - 5) - 5 = 45 - 20 - 5 = 20%
3.) % non of the beverage types = 100 - 20 - 20 - 5 - 10 - 20 - 5 = 20%
