Using a system of equations, it is found that 41 regular and 53 sleeper seat tickets were sold.
<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Regular coach seats.
- Variable y: Sleeper cars seats.
94 passengers rode in a train from City A to City B, hence:
Tickets for regular coach seats cost 115$. Tickets for sleeper cars seats cost 281$. The receipts for the trip totaled 19,608$, hence:
From the first equation, x = 94 - y, hence, replacing on the second.
Hence, 41 regular and 53 sleeper seat tickets were sold.
