Tickets to a school dance cost $5. Ninety tickets have already been sold.
How many more tickets x must be sold to earn at least $700?
Write your answer as an inequality
:
let x = no. of tickets
:
5x + 5(90) => 700
5x + 450 => 700
5x => 700 - 450
5x => 250
x => 250/5
x => 50 tickets
:
At least 50 more tickets have to be sold
