Let as consider, we need to find the fixed fee.
Given:
Cost of each ticket = $18
Number of tickets = 5
Total cost = $93
To find:
The fixed fee.
Solution:
Let x be the fixed fee..
Cost of 1 ticket = $18
Cost of 5 ticket = $(5 × 18)
= $90
Total cost 5 tickets = Fixed fee + Cost of 5 tickets
[tex]93=x+90[/tex]
[tex]93-90=x[/tex]
[tex]3=x[/tex]
Therefore, the fixed fee is $3.
