What is the formula.[utilizing cells]?

The following information applies to the products of Corbett Company. \begin{tabular}{l|c|cc|} \hline & Product A & Product B \\ \hline Selling price per unit & $40.00 & $ & 32.00 \\ Variable cost per unit & $24.00 & $ & 12.00 \\ \hline \end{tabular} Identify the product that should be produced or sold under each of the following constraints. Consider each constraint separately. - One unit of Product A requires 2 hours of labor to produce, and one unit of Product B requires 4 hours of labor to produce. Due to labor constraints, demand is higher than the company's capacity to make both products. - The products are sold to the public in retail stores. The company has limited floor space and cannot stock as many products as it would like. Display space is available for only one of the two products. Expected sales of Product A and Product B are 8,000 units and 9,000 units, respectively. - The maximum number of machine hours available is 40,000 . Product A uses 2.50 machine hours, and Product B uses 4 machine hours. The company can sell all the products it produces. \begin{tabular}{|r|r|r|} \hline 2 & 4 & \\ \hline & & \\ 8,000 & 9,000 & \\ \hline 40,000 & 2.50 & 4 \\ \hline \end{tabular} Required Complete the spreadsheet.
