Final answer:
To break-even with a fixed rental fee of $2,100 per month, the operator of a Spicyfruit cart must sell 700 smoothies, as the contribution margin per smoothie is $3.00, which accounts for the price minus the variable cost.
Step-by-step explanation:
The subject of this question is related to break-even analysis in the context of a business operation. Specifically, we need to calculate the number of smoothies that the operator of a Spicyfruit cart must sell to break-even with the first option of a fixed rental fee of $2,100 per month.
To do this calculation, we need to consider the fixed costs and the contribution margin. The fixed cost here is the monthly rental fee of $2,100. The contribution margin is the price of one smoothie ($4.00) minus the variable cost of one smoothie ($1.00), which equals $3.00.
To calculate the break-even point in units, we divide the fixed cost by the contribution margin per unit:
Break-even point in units = Fixed costs / Contribution Margin per unit
Break-even point in units = $2,100 / $3.00
Break-even point in units = 700 smoothies.
Therefore, the operator would need to sell 700 smoothies in a month to break-even, making option B the correct answer.
