Statement Problem: The tickets for a play sold out in 2.5 hours. If there were 20,000 tickets sold, solve the equation;
[tex]20000-2.5x=0[/tex]to find the number of tickets sold per hour.
Solution:
Given the equation;
[tex]20000-2.5x=0[/tex]Where x is the number of tickets sold per hour.
Then, add 2.5x to both sides;
[tex]\begin{gathered} 20000-2.5x+2.5x=0+2.5x \\ 20000=2.5x \end{gathered}[/tex]Next, divide both sides of the equation by 2.5 ;
[tex]\begin{gathered} \frac{20000}{2.5}=\frac{2.5x}{2.5} \\ x=8000 \end{gathered}[/tex]The number of tickets sold per hour is 8000
