Answer:
90909 pieces of elf bread
Step-by-step explanation:
666 divided by 888 is .75
.75 times 121212 is 90909
Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12
The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10
There were originally 10 people on team Alpha.
