Question

During a film festival, the first film ticket is priced at 16 dollars, and each additional ticket is 11 dollars. If rico spend 71 dollars, then how many film tickets di he purchase?

Answer 1

He purchases a total of 6 tickets: $16 for the first and $5 each for 5 more tickets.

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
