Austin wants to make twelve gallons of 46% acid solution by mixing together 65% acid solution and a 5% acid solution. How much of each solution should he use?

acid of ngredients = acid content of final soln

 

.65 x   +  .05(12-x)  = .46 (12)      solve for x   the amount of 65% solution gallons  then 5% amount = 12-x gallons.
