Answer 1

Statement Problem: The tickets for a play sold out in 2.5 hours. If there were 20,000 tickets sold, solve the equation;

`20000-2.5x=0`

to find the number of tickets sold per hour.

Solution:

Given the equation;

`20000-2.5x=0`

Where x is the number of tickets sold per hour.

Then, add 2.5x to both sides;

`\begin{gathered} 20000-2.5x+2.5x=0+2.5x \\ 20000=2.5x \end{gathered}`

Next, divide both sides of the equation by 2.5 ;

`\begin{gathered} (20000)/(2.5)=(2.5x)/(2.5) \\ x=8000 \end{gathered}`

The number of tickets sold per hour is 8000
