it cost 660 to put on the school play. how many tickets must be sold at 6 piece in order to make a profit?

> 660/6

To determine the number of tickets that must be sold to make a profit, we need to consider the cost of putting on the school play and the revenue generated from ticket sales.

1. First, let's calculate the cost of putting on the school play: $660.

2. Next, we need to determine the revenue from ticket sales in order to cover the cost and make a profit. Each ticket is sold for $6.

To find the number of tickets to be sold, we can use the following formula:

Number of tickets = Cost / Price per ticket

Number of tickets = $660 / $6

Number of tickets ≈ 110

So, approximately 110 tickets must be sold at $6 per ticket in order to cover the cost of $660 and make a profit.
