Question

A chemist needs 10L of 21% salt solution. The chemist has two salt solutions availible at 15% and 25% salt. Write a solve a linear system to find the volume of each solution that needs to be combined to make the mixture

Answer 1

let volume of one solution = x
volume of other solution=(10-x)
(15/100)x + (25/100)(10-x) = (10)(21/100)
0.15x + 2.5 -0.25x=2.1
1x=0.4
x=0.4 L
10-x= 0.6 L
