Write an inequaility to describe this situation. A student pays for three movie tickets with a twentu dollar bill and gets change back. Let t be the cost a a movie ticket.
t is the price of the movie ticket. We know that 3 tickets is less than twenty dollars, because the student got change back.
3t < 20
3t < 20
To write an inequality to describe this situation, we need to consider the fact that the student pays with a twenty dollar bill and gets change back. Let's assume the cost of a movie ticket is represented by 't'.
The student pays for three movie tickets, so the total cost of the tickets would be 3*t. Since the student pays with a twenty dollar bill, the amount of change received can be calculated as (20 - 3*t).
However, we are looking for an inequality, so we need to consider the inequality between the amount of change and zero dollars. If the student receives any money back, it means the cost of three movie tickets is less than twenty dollars. Therefore, we can write the inequality as:
(20 - 3*t) > 0
This inequality states that the change received by the student is greater than zero, indicating that the cost of three movie tickets is less than twenty dollars.
