In 2006, the price of king crab was $8 per pound at
the beginning of the year and dropped to $7
per pound toward the end of the year. if 60% of the
king crab supply was sold at the higher price per
pound and the rest was sold at the lower price per
pound, what was the total revenue generated, in
millions of dollars, from the sales of king crab in
2006 ? (disregard the $ when gridding your answer.)

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
