Problem Analysis

We are given that a store received 100 football and volleyball balls. The number of football balls is 20 more than the number of volleyball balls. We need to determine how many football and volleyball balls were brought to the store.

Solution

Let's assume the number of volleyball balls is x. According to the problem, the number of football balls is 20 more than the number of volleyball balls, so the number of football balls is x + 20.

We know that the total number of balls is 100, so we can write the equation:

x + (x + 20) = 100

Simplifying the equation:

2x + 20 = 100

Subtracting 20 from both sides:

2x = 80

Dividing both sides by 2:

x = 40

Therefore, there were 40 volleyball balls and 40 + 20 = 60 football balls brought to the store.

Answer

The store received 40 volleyball balls and 60 football balls.
