A scientist needs to make 2 liters of saline solution (salt water), in which the salt
level must be at 15% concentration (meaning 15% of the water is salt).
Unfortunately, the scientist only has two types of saline solution in his
possession. He has saline solution with a 10% concentration level and saline
solution with a 35% concentration level.
10
How much of each type of saline solution should the scientist mix together to
achieve 2 liters of saline solution at a concentration level of 15%?
11
Let I represent the amount 10% saline solution and let y represent the amount
of 35% saline solution.
