Answer:

The cost of the old ball was $100.

Step-by-step explanation:

The cost of the new ball = $300

The new ball has three times the price of his old ball.

So, let the price of the old ball be = x

As per situation, we get the equation:

$3x=300$

Dividing both sides by 3:

$\frac{3x}{3}= \frac{300}{3}$

=> x = 100

Hence, the cost of the old ball was $100.
