5/7 which means for every 7 kids, one owns a dog
"Bucket method"
.. (4)*(14%) + (x)*(8%) = (4 +x)*(10%) . . . . . liters and % are in each "bucket"
.. 56 +8x = 40 +10x . . . . . multiply by 100, eliminate parentheses
.. 16 = 2x . . . . . . . . . . . . . . add -40-8x, then divide by 2
.. 8 = x
8 liters of 8% lemonade should be added to make the mixture 10% lemon juice.
Step-by-step explanation:
Let each let of chicken be C and dog be D respectively.
Then as per question
2C+4D = 28.......i
and
C-D =14........ii
These are the two algebraic equation which you are looking for solve them
to get the answer
