On Saturday, Bianca has $50 on her debit card when she goes out with some friends. She uses her debit card to spend $14.50 on lunch. She and her friends would like to go to see a movie, but some of her friends are out of money.
If the movie tickets cost $6.50 each, write an inequality to represent the number of tickets Bianca can buy without overdrawing on her debit card.
