Lakewood baseball team is selling T-shirts for a fundraiser. The shirts cost $100 for the printing design and set up plus $10 per shirt. The team is going to sell the shirts for $15 each. How many shirts do they need to break even

To break even, the total revenue from selling shirts must cover the total cost of printing plus the cost per shirt.

Let x be the number of shirts sold.

Total cost = $100 + $10x (printing design/set up cost + cost per shirt)
Total revenue = $15x

To break even:
$100 + $10x = $15x

Solving for x:
$100 = $5x
x = 20

Therefore, the team needs to sell 20 shirts to break even.
