Problem
A field-trip bus costs \(\$185\), and admission is \(\$7~\text{for}~\text{each}\) of \(28~\text{students}\). Calculate the result, give its unit, and interpret what it means.
Big Picture
What this problem is really about
Build the trip total from two different cost structures: one fixed bus charge and a per-student admission charge repeated for every student. Calculate the admission subtotal first, add the fixed transportation cost, and track dollars throughout. The final interpretation must describe the combined bus-and-admission expense, not either component by itself.
