Answer:
Hilary is a retired teacher who lives in Miami and does some consulting work for extra cash. At a wage of $50 per hour, she is willing to work 10 hours per week. At $65 per hour, she is willing to work 19 hours per week.
Using the midpoint method, the elasticity of Hilary’s labor supply between the wages of $50 and $65 per hour is approximately 2.37 , which means that Hilary’s supply of labor over this wage range is elastic.
Explanation:
Midpoint elasticity = (Change in labor supplied / Average labor supplied) / (Change in wage rate / Average wage rate)
= [(19 - 10) / (19 + 10) / 2] / [$(65 - 50) / $(65 + 50) / 2]
= [9 / (29 / 2)] / [15 / (115 / 2)]
= (9 / 14.5) / (15 / 57.5)
= 0.62/0.26
Midpoint elasticity = 2.37
Once elasticity is greater than 1, supply of labor is Elastic.
Answer:
since the price elasticity of demand for students is -4, the the price charged to them should be:
price = [-4 / (-4 + 1)] x $6 = (-4 / -3) x $6 = $8
since the price elasticity of demand for faculty is -2, the the price charged to them should be:
price = [-2 / (-2 + 1)] x $6 = (-2 / -1) x $6 = $12
Answer:
B. Portfolio B with E(R)=13% and STD=18%
Explanation:
The computation is shown below;
Reward to risk ratio = (15% - 5%) ÷ 20% = 0.5
The porfolio should be in line i.e.
= 0.05 + 0.5 × standard deviation
For portfolio A
= 0.05 + 0.5 × 25
= 17.5%
For portfolio C
= 0.05 + 0.5 × 1
= 5.5%
Portfolio B, the std is 18%
So,
= 0.05 + 0.5 × 18%
= 14%

Explanation:
Decision grids are valuable tools because they help us:
- Evaluate and prioritize a list of options
- Make the best choices at the least cost
- Make wise decisions in a range of contexts
- Consider the cost and benefits of a decision
- Reduce subjectivity to help make sound conclusions
- See what we gain and lose by choosing between alternatives
