Chandra needs 230 liters of a 37% solution but she has only 15% and 61% solutions
available.
Answer provided by our tutors
Let
x = liters of the 15% solution
y = liters of the 61% solution
x + y = 230
0.15x + 0.61y = 0.37*230

........
x = 120 l
y = 110 l
Chandra will have to use 120 liters of the 15% and 110 liters of the 61% solution.
