Answer:
(b) R + S = 3540
(c) 5R + 2S = 9024
Explanation:
You want two equations to describe the relations ...
- a total of 3540 Reserved seat and Student tickets were sold
- at $5 for a Reserved seat and $2 for a Student ticket, revenue totaled $9024.
Equations
Using R for the number of Reserved seat ticket sold, and S for the number of Student tickets sold, the total number sold is described by the equation ...
R + S = 3540 . . . . . . . . total ticket sold
The revenue from the sale of each kind of ticket is the product of the ticket price and the number of tickets. Adding these products gives the total revenue:
5R +2S = 9024 . . . . . . dollar amount of ticket sales
