Respuesta :
The ball costs ten cents. If the total cost is $1.10 and the bat costs $1 more than the ball then the only logical cost for the ball is $0.10 because $1 +$0.10= $1.10, which is the cost we are looking for.
the ball costs 5 cents. 1.05+.05=1.10 (1.05=the price of the bat, .05= the price of the ball)
