American Auto is evaluating their marketing plan for the sedans, SUVs, and trucks they produce. A TV ad featuring this SUV has been developed. The company estimates each showing of this commercial will cost $$500,000$ and increase sales of SUVs by $3\%$ but reduce sales of trucks by $1\%$ and have no effect of the sales of sedans. The company also has a print ad campaign developed that it can run in various nationally distributed magazines at a cost of $$750,000$ per title. It is estimated that each magazine title the ad runs in will increase the sales of sedans, SUVs, and trucks by $2\%,1\%,$ and $4\%,$ respectively. The company desires to increase sales of sedans, SUVs, and trucks by at least $3\%,14\%,$ and $4\%,$ respectively, in the least costly manner.
