Jeffrey has been successful with his small business that he is planning to expand his shop. He is going to start enlarging the shop by purchasing a larger equipment. For the following data:
Original size: 25 gal
New size: 50 gal
Power sizing exponent: 0.2
Cost of the 25 gal equipment 10 years ago: $1500
Cost Index 10 years ago 150
Cost Index today: 200
A- if the Cost of the new 50 gal equipment 10 years ago is $1700 the Cost of the new 50 gal equipment today is closest to:
$2,267 |
$2,324 |
$2,258 |
$2,291 |
B-Cost of the new 50 gal equipment 10 years ago is closest to:
$1,723 |
$1,715 |
$1,717 |
$1,742 |
A- Cost of the product in the current year= Cost of the product in base year/(Cost index in Base year/Cost index in current year)
Here given cost of new 50 gal equipment 10 years ago = $1700
Cost index 10 years ago= 150
Cost index in current year = 200
Cost of new 50 gal equipment in current year = 1700/(150/200) = $2266.666 which is nearest to the value $2,267.
B- Using power sizing exponent value, cost of 50 gal equipment 10 years ago or in base year = Cost of 25 gal equipment 10 years ago/(Size of equipment 10 years ago/size of equipment in current year)n Here n= power sizing exponent value = 0.2
Cost of 25 gal equipment 10 years ago = $1500
Size of equipment 10 years ago = 25 & size of equipment in current year = 50
Therefore cost of 50 gal equipment 10 years ago = 1500/(25/50)0.2 = $1723.04 which is nearest to $1723.
