Final answer:
The cost of the tennis racket is $52.63.
Step-by-step explanation:
To find the cost of the tennis racket, we can set up an equation.
Let's assume the cost of the tennis racket is 'x' dollars.
Since the total cost of the tennis racket and a can of balls is $159.89, we can write the equation: x + can of balls = $159.89
We don't have the cost of the can of balls, but we know that the cost of the racket is the only option given, so we can substitute the value of the racket's cost into the equation:
x + can of balls = $159.89
x + can of balls = $52.63 + can of balls
x = $52.63
Therefore, the cost of the tennis racket is $52.63.
