Answer:
He purchases a total of 6 tickets: $16 for the first and $5 each for 5 more tickets.
Step-by-step explanation:
Here we need an equation with a constant term and a variable term:
$71 total = $16 + ($11/ticket)*(t tickets)
Subtracting $16 from both sides, we get
$55 + ($11/ticket)*(t tickets)
Dividing both sides by ($11/ticket)
results in
$55
-------------- = 5 tickets (beyond the first one)
$11/ticket
