In 105 months, your solution will equate to the cost savings offered by the vendor. In other words, if your solution will be kept longer than 105 months, it's best to use your solution. You can find this solution by first finding the difference of the build and buy costs, which is $47,000. Next, find the difference of the monthly costs, which is only $450. You'll then divide $47,000 by $450 for an answer of 104.4 months, or for this answer, 105 months. Answer: C is incorrect. 64 months is not the correct calculation to this scenario. Answer: B is incorrect. 32 months is not the correct calculation to this scenario. Answer: D is incorrect. 19 months is not the correct calculation to this scenario.
