Let highlight_green%28x%29represent How many gallons of a 25% chemical solution must be added

Mixing the 25% and 50% to get 30% solution:

*** .25x+%2B+.50%2A60gal+=+.30%2860gal%2Bx%29  |Solve for x

      .20*60gal/.05 = x = 240gal, the gallons of 25% solution to add

 CHECKING our answer***

 60gal + 30gal = .30*300gal = 90gal

Wish You the Best in your Studies.
