Linear Systems Word Problems- Part 4

Here is the last linear systems word problem... also one of the most challenging linear word problem in my opinion... this is one of those 1% solution crap... so yeah... here's the problem

To conduct a scientific experiment, students need 90 milliliters of a 3% acid solution. They have a 1% and 10% solution available. How many milliliters of the 1% solution and the 10% solution should be combined to produce 90 milliliters of a 3% solution?

This is a very confusing problem... and in the video i explain it. If you don't get it, don't get discouraged.. It took me quite a while to understand this so don't feel bad. :)
