Kim spends $25,000 to open a store. She makes $4000 a month in revenue and her expenses are $1500 a month. How long would it take to pay back the cost to open the store? Give me reasons, before answering the question
Her profit is 4000 - 1500 = $2500. So it takes 25000 / 2500 = 10 months to make back the money. So the final answer is 10.
