Answer:
The demand for cereal is elastic.
The demand for the magazine is inelastic.
Explanation:
The price elasticity of demand is the degree of responsiveness of quantity demanded to change in price. A negative price elasticity implies that the product is a normal good.
The price elasticity of demand for cereal is −1.03. This means that the demand is price elastic. An elastic demand implies that a change in price will cause more than proportionate change in quantity demanded.
The price elasticity of demand for a particular magazine is −0.72. This means that the demand is price inelastic. An inelastic demand implies that a change in price will cause less than proportionate change in the quantity demanded.
Solution:
Given Information,
Heat input is ( 
) = 5.5 × 
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler 
= x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
= / 
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
= -
= 5.5 x - 4.8125 x Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( 
)
= x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = 
x Unit cost
= 3575 x Btu/h x
= 82225
Answer: A. Managers scan their firm's environment to reduce uncertainty.
Explanation: In the context of the external environment of a firm, managers scan their firm's environment to reduce uncertainty.

Arguments supporting Affirmative Action:
1) Affirmative action is a method that ensure the diversity is obtained and maintained in schools and workplaces. Moreover, it also helps to create tolerant communities therefore, it exposes people to a variety of cultures and ideas that are different from their own.
2)Affirmative action assists disadvantaged people that come from areas of the country where opportunities are limited be able to advance and they otherwise could not. In other words, it bestows everybody the same playing field.
3)Affirmative action is for to help by compensating to some races who are"started late in the race" , due to many years of oppression, and it also helps level the playing field.
Arguments against Affirmative Action:
1) Affirmative Action can be described as reverse discrimination. More specifically, past discrimination against some minority groups does not justify existing discrimination against them.
2) It weakens the notion of meritocracy and instead weakens races as a dominant factor in recruitment and recruitment procedures. Regardless of the situation, the best people for the position should be placed there.
3) Students / staff involved in the approval process are often not fully prepared for the assignment.
4) Affirmative Action strengthens stereotypes and racism compared to the previous point. People who give a position almost positively because of their activity are often unsuitable and the idea that all people in this race are "stupid" is endless.
5) People of different races or ethnic backgrounds do not need to have differences of opinion in the workplace / university. People with the same skin color are not necessarily the same in terms of vision or culture.
