A sports-equipment factory produces sports balls. On Monday, they produced 1,080 balls altogether. All of the balls they produced were either volleyballs or soccer balls. They produced 7 times as many volleyballs as soccer balls. How many soccer balls did the factory produce on Monday?

Answer: 135 soccer balls

Step-by-step explanation:

In this equation, let x represent the number of soccer balls, and 7x represent the number of volley balls.

7x + x = 1,080

8x = 1,080

Now divide 1,080 by 8 to get the number of soccer balls.

1,080 / 8 = 135

In case you're wondering how to find the number of volley balls, just multiply 135 by 7

135 * 7 = 945
