The model equation y = b + mx can be used to calculate the total money spent in a park given the number of games. By substituting values into the equation, the expenditure can be computed quickly.
The model equation that represents the scenario is: y = [tex]$10 - $[/tex]2 imes Q_{ ext{burgers}} - [tex]$0.50 imes Q_{ ext{bus tickets}}
Using this equation, you can calculate the total money spent at the park for a specific number of games:
For example, if a person buys 3 games:
Total money spent = $[/tex]10 - [tex]$2 imes 3 - $[/tex]0.50 imes 3 = [tex]$10 - $[/tex]6 - [tex]$1.50 = $[/tex]2.50
