Question

Cortez had 5 bouncy balls and bought 5 more. Duane had 8 bouncy balls and

also bought some more. They now have the same amount of bouncy balls.

Answer 1

x = 2

Explanation:

To solve this problem, we can use algebra. Let's let "x" represent the number of bouncy balls that Duane bought.

Before buying more balls, Cortez had 5 bouncy balls. After buying 5 more, he has a total of 5 + 5 = 10 bouncy balls.

Before buying more balls, Duane had 8 bouncy balls. After buying "x" more, he has a total of 8 + x bouncy balls.

We know that they now have the same number of bouncy balls, so we can set up an equation:

⇒ 10 = 8 + x

Solving for "x", we can subtract 8 from both sides:

⇒ 10 - 8 = x

⇒ 2 = x

Therefore, Duane bought 2 more bouncy balls. To check, we can see that after buying 2 more, Duane has a total of 8 + 2 = 10 bouncy balls, which is the same as Cortez.

Answer 2

Duane bought 2 bouncy balls
