To find out how many tickets Salar can buy, we would need to divide the money he has, for spending, by the cost of each ticket-first. This would look like:

Or

When simplified, the quotient (answer for a division problem) would be 4.357143.
4.357143 is not a whole number. Let's round it to nearest whole number: 4. After all, Salar can't exactly buy 4.357143 tickets. He would have to tear a ticket.
So, with $15.25, Salar can buy 4 tickets for the play.
