Final answer:
To calculate the number of tubs that must be sold for revenue, we need to consider the fixed costs and the profit. The club must sell 25 tubs to reach the revenue goal.
Step-by-step explanation:
To calculate the number of tubs that need to be sold for revenue, we need to consider the fixed costs and the profit. The fixed cost is the booth cost of $100, and the profit is the selling price minus the cost price of each tub, which is $5 - $1 = $4. Let's assume that the number of tubs sold is 'x'. The revenue earned can be calculated as:
Revenue = Selling Price imes Number of Tubs
Now, since the fixed cost needs to be covered, the equation becomes:
$100 + (Selling Price - Cost Price) imes Number of Tubs = Selling Price imes Number of Tubs
Simplifying this equation, we have:
$100 = (Selling Price - Cost Price) imes Number of Tubs
Substituting the given values, we get:
$100 = $4 imes x
Solving this equation, we find:
x = $100 / $4 = 25
Therefore, the club must sell 25 tubs in order to reach the revenue goal. Hence, the answer is option B) 25 tubs.
