A bat and a ball cost $1.10 in total. The bat c

Let's call the cost of the ball "X" in dollars. According to the information given, the bat costs $1.00 more than the ball, so the cost of the bat is X + $1.00.

Now, we know that the total cost of the bat and the ball is $1.10. So, we can set up an equation:

X (cost of the ball) + (X + $1.00) (cost of the bat) = $1.10

Now, we can combine like terms:

2X + $1.00 = $1.10

Subtract $1.00 from both sides of the equation:

2X = $1.10 - $1.00

2X = $0.10

Now, divide both sides by 2 to solve for X (the cost of the ball):

X = $0.10 / 2

X = $0.05

So, the ball costs $0.05 or 5 cents.
