You have been offered the chance to invest in a quick no$-$frills promotion scheme. The entry fee is $$350000$ and the venture is to capitalise on the fame of the Star Wars film franchise, given the great success of the movies. Y'ou will produce Star Wars costumes. The promoter offers investors $$120000$ back in four years and $$430000$ in eight years. If investors think they require an $10\mathrm{.}5\%$ return on this type of investment, is this a good investment?
