Final answer:
Jax can buy 8 balls at the sale price because he has enough money to buy 2 balls at the regular price, which is 4 times the sale price.
Step-by-step explanation:
The question asks us to determine how many balls Jax can buy at the sale price given that he has enough money to buy 2 balls at the regular price. We're told that the sale price is one fourth of the regular price.
Let's denote the sale price of the ball as d dollars. The regular price of the ball would then be 4d dollars. Since Jax has enough money to buy 2 balls at the regular price, he has 2 × 4d = 8d dollars.
At the sale price of d dollars per ball, Jax can divide the total amount of money he has (8d dollars) by the sale price (d dollars) to find out how many balls he can buy:
8d ÷ d = 8 balls
Therefore, Jax can buy 8 balls at the sale price.
