Price elasticity can be calculated using the attached formula where:
the first term represents the % change in quantity and the second term represents the % change in price
% change in quantity = (100-120) / (220/2) = -2/11 x 100 = -18.1818%
% change in price = (7-5) / (12/2) = 33.3333%
price elasticity = 18.1818/33.3333 = 0.55Note that the price elasticity is usually taken as an absolute value.
Answer:
$15.43
Explanation:
Following actions are required for triangular arbitrage:
Available: $ 10,000
Buy sterling pound @ 1 $ = 1.62 pounds and receive pounds 6172.84 upon conversion.
Now, sell these pounds and purchase NZ $ at the rate :
1 pound = NZ $ 2.95 and receive NZ$ 18209.87
Now, reconvert the above proceeds into US $ at the rate
1 NZ $ = $0.55 i.e sell NZ $ at this rate and receive US $ 10,015.4285
Hence profit from implementing triangular arbitrage is $10,015.43 - $10,000
= $15.43
Arbitrage refers to the prospect of earning a profit by utilizing the mispricing in two different financial markets. An arbitrageur never uses his own funds and always borrows.
Arbitrage works only in the scenario wherein the interest rate purchase parity (IRPT) does not hold good.
The strategy of arbitrage is best explained as "Buy at low price and sell at a high price".

Answer:
The correct answer is option B.
Explanation:
The total revenue and profits of the industry as the price level increases with increase in the demand.
When there is an increase in the demand for the output of an industry, that industry will increase the production to match the increase in the demand. The increase in production will cause output level to increase.
In order to produce more output the industry will require more inputs, so the demand for inputs will increase.
An increase in the demand for inputs will be accompanied by increase in their prices.
There will not be any decline in the price of inputs.
Answer:
D. $100
Explanation:
Given: William install 7 system per day at the cost of $300.
William install 8 system per day at the total cost of $400.
Remember, If the marginal cost curve is upward-sloping, this means that as output increase, marginal costs will also increase.
Marginal cost is an additional cost incurred in producing additional unit of output.
Now, finding additional payment that eighth customer has to pay.
Change in marginal cost= 
⇒ Change in marginal cost= 
∴ Change in marginal cost= 
Hence, there is an increase in marginal cost by $100 as output increases, therefore, William will install eight sound systems per day only if the eighth customer is willing to pay at least $100.
