Man these are so tough to find the equation for me.
Here's the problem, I just want a push in the right direction to find the equation:
How many grams of sugar must be added to 60 grams of a solution that is 32% sugar to obtain a solution that is 60% sugar?
Hello, Jonboy!
I usually place these "Mixture Problems" in a chart.
How many grams of sugar must be added to 60 grams
of a solution that is 32% sugar to obtain a solution that is 60% sugar?
Make a chart.
Make one row for the Original solution, one for the Added solution, one for the Mixture.
We have 60 grams of solution which is 32% sugar.
. . It has: . grams of sugar.
Write that in the first row.
We will add grams of sugar (which is 100% sugar, of course).
. . It has: . grams of sugar.
Write that in the second row.
The Mixture will have grams of solution which is 60% sugar.
. . It has: . grams of sugar.
Write that in the third row.
The equation is waiting for us in the last column: .
. . . Got it?
