Question

There are three times as many people at the baseball park today than there were yesterday. Today’s attendance is 15,000. Define a variable and then write an equation to find yesterday’s attendance.

Answer 1

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance

Step-by-step explanation:

There are three times as many people at the baseball park today than

there were yesterday

Assume that the number of the people at the baseball park

yesterday is x

∵ The number of the people at the baseball park yesterday = x

∵ The number of people at the baseball park today is three times

   as many as the number of the people yesterday

∴ The number of people at the baseball park today = 3 x ⇒ (1)

∵ Today’s attendance is 15,000

∴ The number of people at the baseball park today = 15,000 ⇒ (2)

- Equate (1) and (2)

∴ 3 x = 15,000

- To find the value of x solve the equation:

  3 x = 15,000

The equation is:

3 x = 15,000 where x is the number of yesterday’s attendance
