Question

Pine Bluff Middle School is having its annual Spring Fling dance, which will cost $400. The student treasurer reported that the dance fund has $ 75 left over from last year. Each ticket to the dance costs $4. Let t represent the number of tickets sold. Write an inequality to determine how many tickets must be sold to pay for this year's dance.

Answer 1

First you subtract the current fund from the total cost
400 - 75 = 325
Then you divide 325 by the price of the tickets 4, for the number of tickets needed
325/4= 81.25
Since you can't sell a quarter of a ticket, 81.25 is rounded up to 82
x ≤ 82
