Answer:
a. Due to increases in hay prices, an input for raising cattle, the price of a gallon of 2% milk increases from $2.98 to $3.25. QUANTITY DEMANDED DECREASES, as the price of a good or service increases, the quantity demanded decreases.
b. Groupon has a Groupon for $6 off the price of laser tag. QUANTITY DEMANDED INCREASES, as the price of a good or service decreases, the quantity demanded increases.
c. Sharp increase in the price of wood causes increases in prices for dressers and desks. QUANTITY DEMANDED DECREASES, if the price of a key input increases, the production costs will increase, resulting in a higher selling price ⇒ lower quantity demanded.
d. Week long special at the grocery store, where pork shoulder is on sale at $1.99 a pound, down from $3.99 a pound. QUANTITY DEMANDED INCREASES, as the price of a good or service decreases, the quantity demanded increases.
e. Buy one get one free special for MP3 albums on Amazon. QUANTITY DEMANDED INCREASES, the buy one get one free promotion lowers the price of a good or service, resulting in higher quantity demanded.
Answer: Option (a) is correct.
Explanation:
Income elasticity of demand measures the responsiveness of quantity demanded with change in the income level of an individual.
Income of an individual has a positive relationship with the demand for normal goods and has a negative relationship with the demand for inferior goods.
Answer:
The net present value of the machine is $5530
Explanation:
Data provided in the question:
Cost of the equipment = $84,000
Annual after-tax net income from the equipment after deducting depreciation = $3,000
Depreciation = $28,000
Useful life = 3 years
Required return on investment = 9% = 0.09
Now,
After-tax cash flow = After-tax net income + Depreciation
= $3,000 + $28,000
= $31,000
Therefore,
Net Present Value = Present value of cash flow - Investment
= ( $31,000 × PVIFA(11%, 3)
) - $84,000
= ( $31,000 × 2.5313 ) - $84,000
= $78470.3 - $84,000
= -$5529.7 ≈ - $5530
hence,
The net present value of the machine is $5530
