Brown's, a local bakery, is worried about increased costs particularly energy. Last year's records can provide a fairly good estimate of the parameters for this year. Wende Brown, the owner, does not believe things have changed much, but she did invest an additional $2,500 for modifications to the bakery's ovens to make them more energy efficient. The modifications were supposed to make the ovens at least 20% more efficient. Brown has asked you to check the energy savings of the new ovens and also to look over other measures of the bakery's productivity to see if the modifications were beneficial. You have the following data to work with: Last Year Now Production (dozen) 1,500 1,500 Labor (hours) 350 325 Capital Investment ($) 16,000 18,500 Energy (BTU) 3,200 2,800 1)Energy productivity increase = enter your response here% (enter your response as a percentage rounded to two decimal places and include a minus sign if necessary). 2)Capital Productivity increase= (enter your response as a percentage rounded to two decimal places and include a minus sign if necessary). 3)Percentage productivity increase based on "Labor" = enter your response here% (enter your response as a percentage rounded to two decimal places and include a minus sign if necessary

Question

Brown's, a local bakery, is worried about increased costs particularly energy. Last year's records can provide a fairly good estimate of the parameters for this year. Wende Brown, the owner, does not believe things have changed much, but she did invest an additional $2,500 for modifications to the bakery's ovens to make them more energy efficient. The modifications were supposed to make the ovens at least 20% more efficient. Brown has asked you to check the energy savings of the new ovens and also to look over other measures of the bakery's productivity to see if the modifications were beneficial. You have the following data to work with:

	Last Year	Now
Production (dozen)	1,500	1,500
Labor (hours)	350	325
Capital Investment ($)	16,000	18,500
Energy (BTU)	3,200	2,800

1)Energy productivity increase = enter your response here% (enter your response as a percentage rounded to two decimal places and include a minus sign if necessary).

2)Capital Productivity increase= (enter your response as a percentage rounded to two decimal places and include a minus sign if necessary).

3)Percentage productivity increase based on "Labor" = enter your response here%
(enter your response as a percentage rounded to two decimal places and include a minus sign if necessary).
