As each ticket costs $50 and she wants to buy 3 tickets.
3*$50= $150 (total amount)
3 tickets would be of ($135+$15)= $150.
So that means she borrowed $15 from a bank and she is le with -$15.
Understand that when representing a debt with a negative number, the additive inverse tells how much money is needed to pay off the debt.
