Multiple Choice

Use the following information to answer the questions) below.
Cerebro Manufacturing produces four types of structural support fittings-plugs, rails, rivets, and clips-which are machined on two CNC machining centers. The machining centers have a capacity of 250,000 minutes per year. The gross margin per unit and machining requirements are shown in the spreadsheet below. $\begin{array}{|l|l|l|l|l|l|l|} \hline&{\text { A }} & \text { B } &C&D&E&F\\\hline 1 & \text { Cerebro } & \\ & \text { Manufacturing Model } & \\\hline 2 & & \\\hline3 & \text { Product } & \text { Plugs } & \text { Rails } & \text { Rivets } & \text { Clips } &\begin{array} { l } \text { Machine } \\\text { Capacity } \\\text { mins./year) } \\\end{array}\\\hline 4 & \text { Gross margin/unit } & \$ 0.40 & \$ 1.20 & \$ 0.80 & \$ 1.10 & \\\hline 5 & \text { Minutes/unit } & 1 & 2 & 3 & 1.5 & 250,000 \\\hline 6 & \text { Gross margin/minute } & & & & & \\\hline 7 & \text { Maximum production } & & & & & \\\hline 8 & \text { Profit } & & & & & \\\hline\end{array}$
