Answer 3

Tennis racket and ball pricing

To determine the cost of the ball, let's set up an equation based on the given information. We know that the racket and ball together cost $3, and the racket is $1 more expensive than the ball.

Let's assume the cost of the ball is x dollars. Since the racket is $1 more expensive, its cost would be x + $1.

According to the given information, the total cost of the racket and ball is $3. We can write this as an equation:

x + (x + $1) = $3

Simplifying the equation, we have:

2x + $1 = $3

Subtracting $1 from both sides of the equation, we get:

2x = $2

Dividing both sides by 2, we find:

x = $1

Therefore, the ball costs $1.

Conclusion

Based on the given information, the ball costs $1.
