It's 1.25 and .25 . The price of the bat has to be a dollar more than the price of the bat . If the ball is .50 cents then the bat would be 1.50 . Meaning that in total it would be 2 dollars . Now as for the bat being 1.50 and the ball being 0.00 . The bat has to be a dollar more than the ball. A dollar more than 0.00 is 1.00 . So the ball and the bat together would only be 1.00. When the ball is .25 , the bat would be priced at 1.25. When you add the ball and the bat together (1.25 + .25) the total is 1.50 .
