the candy is worth 1.10 per lb, we have 30lbs of it, so therefore, 30lb * $1.10 per lb = $33.00

Well, we have to equations, we will use the method of sub substitution to solve them. Since we have two unknowns (x and y), we need two equations to solve the system. x + y = 30 lb Solve for x x = 30  y Now we know what x is in terms of y, so lets sub that into our second equation. $1.5y + $0.90x = $33.00 $1.5y + $0.90(30  y) = $33.00 Now we must solve for y
