Priya wants to buy three tickets for a concert. She has earned $135 and each ticket costs $50. She burrows the rest of the money she needs from a bank and buys the tickets. How can you represent the amount of money that priya has after buying the tickets?

-$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.
