Let x be the number of milliliters of 25% solution and y be the number of milliliters of 55% solution.We have the system of equations:x + y = 1500.25x + 0.55y = 0.45(150)Solving this system, we get:x = 50y = 100Therefore, the chemist should mix 50 milliliters of 25% solution and 100 milliliters of 55% solution to get the desired solution.
