Answer:
-$15
Step-by-step explanation:
As each ticket costs $50 and she wants to buy 3 tickets.
3*$50= $150 (total amount)
And, 135/50= 2.7 (no. of tickets)
3 tickets would be of ($135+$15)= $150.
So that means she borrowed $15 from a bank and she is left 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.
