Answer:
A=12 B=11 C=14
Step-by-step explanation:
12(a)+11(b)=23
12(a)+14(c)=26
11(b)+14(c)=25
Write a proportion first, change over original, like this:
8 x
16 100
(I got 8 because the difference between 24 and 16 is 8 and I got 100 because percents are out of 100.)
Cross multiply 8 by 100 and you get 800.
Divide 800 by 16 and you get 50.
It changed by 50%
