Problem
\(\text{Three}~\text{movie}~\text{tickets}\) plus a \(\$4\) service fee cost \(\$25\). Write and solve a two-step equation for the price of \(\text{one}~\text{ticket}\).
Big Picture
What this problem is really about
Separate the repeated ticket cost from the one-time service fee. If x is one ticket’s price, three copies of x plus the fixed four-dollar fee must make the twenty-five-dollar total. Reverse that construction in order—remove the fee first, then divide the ticket subtotal equally among the three tickets—and check both cost parts together.
