Can someone tell me what I'm doing wrong? The answer should be about $413.00 (rounded to the nearest dollar), but I'm getting $433. I'm trying to figure out which company will bring me the most cash flow. The matrix has 3 columns, the time it takes to complete an order, the amount fixed amount I earn per delivery, and an incentive bonus. I receive the day bonus (the incentive) as long as I finish one delivery from the respective company.

Please use the image to help me figure out what I'm not formulating correctly. I'm pretty sure it has something to do with my incentive data since I answered the part before this correctly. (before the incentives were added into the question). Thank You.
