Asteam generation system at a biomass fueled power plant uses an electrostatic precipitator (esp) to clean its gaseous effluents. the power plant has consistently made use of the same type of esp over past several years. the installed cost of a new esp has been relatively constant at $80,000. records of operation and maintenance expenses indicate the following averag expenses per year as a function of the age of the esp the mvs of the esp are also reasonably well known as a function of age.
col1 year 1 2 3 4 5
col2 o& m expense s30,000 $30,000 s35,000 $40,000 s45,000
col3 market value 60,000 50,000 40.000 25,000 12,500
determine the best time to replace the esp if the marr is l 5% per year.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
