Problema Solution
You have two acid solutions one is 8% and the other is 18%, howany gallons of each should mixed together to produce 30 gallons of a solution that is 12% acid. Let x = the gallons of 8% solution and y=18% solution . Write an equation for the total volume of solution. Write an equation for the total volume of acid
Answer provided by our tutors
0.08x + 0.18y = 0.12*30
x + y = 30
by solving the above system of equations we find:
x = 18 gal
y = 12 gal
click here to see the step by step solution of the system of equations:
18 gallons of 8% solution and 12 gallons of 18% solution should be used.
