You can put this solution on YOUR website! Lisa is coloring her creation.
The blue color used is 50% of the green color used,
yellow is 5% of the blue color used,
and brown is 7% of the amount of green used.
She wants to find the total amount of color used by her.
Find the total amount of color used by Lisa using an algebraic expression.
-----------------------
Let amount of green be "x".
Then amt of blue = 0.5x
And amt of yellow = 0.05*0.5x = 0.025x
And amt of brown = 0.07x
-------------------------
Adding those you get 1.595x
-------------------
But nothing relates these percentages to a quantity of paint
or to the whole of the picture. So what does the 1.595x mean?
Whatever the amount of green paint was the rest amounted to
0.595 of it.
