Question

Concert tickets are sold for $15 in advance and $20 at the door. There were 120 tickets sold in advance. Write and solve an inequity to determine how many tickets must be sold at the door for the tickets revenue to be at least $4,000

Answer 1

Without giving the answer, here are the steps you can take to solve the problem

 

Take the known information of the advanced ticket sales 120 tickets * $15 = A

 

Revenue of $4,000 - A = D

 

D/$20 = number of tickets must be sold at the door
