Pick out the needed information
Problem
A group of \(4~\text{friends}\) is buying \(\$9\) tickets to a school play that starts at \(7:30~p.m.\) in a \(120\text{-}\text{seat}\) theater. Identify the information required to calculate the group's total cost.
Big Picture
What this problem is really about
Begin with the requested quantity—total ticket cost—and keep only facts that can determine dollars paid. A units check points to a ticket count paired with dollars per ticket, because those units combine to dollars. Event time and theater capacity add context, but neither changes the group's purchase total.
