Janine is 25 and has a good job at a biotechnology company. she currently has $5,000 in an ira, an important part of her retirement nest egg. she believes her ira will grow at an annual rate of 8 percent, and she plans to leave it untouched until she retires at age 65. janine estimates that she will need $875,000 in her total retirement nest egg by the time she is 65 in order to have retirement income of $20,000 a year (she expects that social security will pay her an additional $15,000 a year). how much will the $5,000 in janine’s ira be worth when she needs to start withdrawing money from it when she retires?

Acompany that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. prior to buying the new equipment, the company used 6 workers, who produced an average of 79 carts per hour. workers receive $16 per hour, and machine coast was $49 per hour. with the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour while output increased by four carts per hour. a) compute the multifactor productivity (mfp) (labor plus equipment) under the prior to buying the new equipment. the mfp (carts/$) = (round to 4 decimal places). b) compute the productivity changes between the prior to and after buying the new equipment. the productivity growth = % (round to 2 decimal places)
