Bianca grows beautiful orchids. Her total fixed cost is $150 a day, and her average variable cost is $1 a plant. Few people know about Bianca's Orchids and she is maximizing her profit by selling 25 orchids a day for $7 a plant. Bianca thinks that if she spends $20 a day on advertising, she can increase her market and sell 44 orchids a day for $7 a plant. If Bianca's belief about the effect of advertising is correct, can she increase her economic profit by advertising?

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
