$0.50 is the answer. If the bat is $1.00 more than the baseball, you would subtract that from the total cost which is $1.50 so the answer would be $0.50.
Write an equation system based on the problem x stands for the bat, and y stands for the baseball "<span>A toy baseball and bat cost $1.50 together" could be written as: </span>∴ x + y = 1.5 "<span>The bat costs $1.00 more than the baseball" could be written as: </span>∴ x = y + 1 <span> Solve the equation system by substitution method. Plug x as y + 1 into the first equation x + y = 1.5 y + 1 + y = 1.5 2y + 1 = 1.5 2y = 1.5 - 1 2y = 0.5 y = 0.5/2 y = 0.25
