Best ResponseYou've already chosen the best response.0This is systems of equations. You find x and y which gives you the amount of gallons of each paint

Best ResponseYou've already chosen the best response.0Okay, but take notes... Using given equations: x + y = 6 .15x + .30y = 6(.25) Write each equation in terms of y as follows: y = 6  x y = (1.5  .15x)/.30 Next set expressions y = y, then cross multiply: .30(6  x) = 1.5  .15x Now solve for x: 1.8  .30x = 1.5 = .15x .3 = .15x .3/.15 = x 2 = x 2 gallons of paint for the 15% gloss Now substitute x back into the original equation to solve for y: 2 + y = 6 y = 6  2 y = 4 4 gallons of paint for the 30% gloss
