A pharmacist mixes 14 ounces of 68% saline solution with 55% saline solution. If the final mixture is 62% saline, how many ounces of the 55% solution were used?

let amount of 55% solution be x ounces
then amount of 68% solution is 14x
solve for x:
.55x + .68(14x) = .62(14)
multiply by 100
55x+ 68(14x) = 62(14)
take over....

55x+68(14x)=62(14)
55x+14368x=868
55x68x=725
