Understanding customer acquisition cost is crucial for any business to evaluate the effectiveness of its marketing efforts. In this scenario, we calculate how much the company spends to acquire one customer. We know that each sales call costs $250, and it takes 5 calls to gain a customer. Therefore, the total cost of making those calls is 5 multiplied by $250, which equals $1,250.
