Answer:
4.15%
Explanation:
In order to determine the annual saving we must divide the extra cost of the hybrid by the amount of years it takes to recoup our investment. 
annual savings = $4,180 / 11 years = $380 per year
our initial investment = -$4,180
since we are going to use the car during 15 years, then we have 15 positive cash flows of $380
using a financial calculator or excel spreadsheet, the internal rate of return (IRR) on our investment = 4.15%

Answer:
private prison enterprise
Explanation:
A public jail is not a profit-generating enterprise. The eventual objective is to house jailed prisoners in an effort to rehabilitate them or remove them from the streets. A private jail, on the other hand, is administered by a business. That corporation’s final purpose is to profit from everything they deal in.
In order to generate money as a private jail, the firm gets into a contract with the government. This contract should indicate the basis for payment to the company. It might be based on the size of the jail, based on a monthly or annual predetermined sum, or in most situations, it is paid depending on the number of convicts that the prison holds.
As of 2019, there are around 116,000 inmates detained in private prisons, which constitutes 8 percent of the overall federal and state prison population.
Many of these jails save the government money, but others actually cost more per prisoner than a public institution would cost.

Mali
b. Which country has the absolute advantage in producing grain?
None
c. Which country has the competitive advantage in producing dates?
Mali
d. Which country has the comparative advantage in producing grain?
Ireland
Explanation: 
Opportunity cost of producing dates:
Ireland = 10 / 5 = 2 tons of grains
Mali = 10 / 25 = 0.4 tons of grains
Opportunity cost of producing grains:
Ireland = 5 / 10 = 0.5 tons of dates
Mali = 25 / 10 = 2.5 tons of dates
