The Spanish club at Santa Fe middle school want to sell mini quiches to raise money for a field trip. The culinary department at their school will make the quiches for $30 plus $0.50 per quiches for the ingredients. The Spanish club wants to sell each quiche for $2 . How many quiches will they need to sell in order to break even?

To break even, the total cost of making the quiches needs to be equal to the total revenue from selling the quiches.

Let's say the number of quiches to be made and sold is represented by x.

The total cost of making the quiches is $30 + $0.50*x.
The total revenue from selling the quiches is $2*x.

To break even, the total cost must equal the total revenue:

$30 + $0.50*x = $2*x

Subtracting $0.50*x from both sides:
$30 = $1.50*x

Dividing by $1.50:
x = $30 / $1.50
x = 20

Therefore, the Spanish club will need to sell 20 mini quiches in order to break even.
