It cost $730 to put on the school play. How many tickets must be sold at $6 apiece in order to make a profit?
Let x be the number of tickets sold
So, the total amount of money we take in = price per ticket x number sold
And we want to make more than $730
So we have
$6x > 730 divide both sides by 6
x > about 121.66 tickets or 122 tickets
