An expansion at fidell, inc., would increase sales revenues by $75,000 per year and cash operating expenses by $38,000 per year. the initial investment would be for equipment that would cost $135,000 and have a 5 year life with no salvage value. the annual depreciation on the equipment would be $27,000. the simple rate of return on the investment is closest to: a.20.0% b.13.3% c.7.4% d.27.4%

definitely a

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
