To calculate the number of quiches the Spanish Club needs to sell in order to break even, we first need to determine the total cost of making the quiches and the total revenue from selling them.
The cost to make the quiches consists of two components: a fixed cost of $30 for the culinary department and a variable cost of $0.50 per quiche for the ingredients.
Let's assume the number of quiches needed to be sold to break even is denoted by 'x'.
The total cost would be:
Fixed Cost + Variable Cost = $30 + ($0.50 * x)
Now for the revenue:
The selling price of each quiche is $2, so the total revenue would be:
Selling Price * Number of Quiches = $2 * x
To break even, the total cost should equal the total revenue:
$30 + ($0.50 * x) = $2 * x
Now we can solve the equation to find the value of 'x'.
Rearranging the equation, we have:
$30 = $2 * x - $0.50 * x
$30 = $1.50 * x
Dividing both sides of the equation by $1.50, we get:
x = $30 / $1.50
x = 20
So, to break even, the Spanish Club needs to sell 20 quiches.
