Answer: (b) -3.08
Explanation:
The relationship between the demand(q), price per unit product(p) and the disposable income,yd is given by the expression below;
q= 20ln(7yd-2p).
From the expression above, the marginal demand,
∂ q/∂ p is the differential of the equation of relationship between the demand, price and disposable income.
This involves considering the demand,q as the dependent variable and the price per unit product,p as the independent variable and the disposable income,yd is considered constant.
Therefore ,
∂ q/∂ p= (-40)÷(7yd-2p)
By substitution of
yd =$3000÷1000= $3
and p= $4
∂ q/∂ p= (-40)÷((7×$3)-(2×$4))
∂ q/∂ p= -40÷13= 3.08
Please see the attachment for knowledge on how ∂ q/∂ p was obtained.
Answer: An investment that matures in five years
Explanation:
Both investments may be of equal risks, but by virtue of having different maturity dates, they will not be priced the same.
This is because the discount rate (opportunity cost) will discount the maturity value more the longer the investment is such that the present value is lower.
4 year investment
= 1,000 / (1.068)^4
= $768.63
5 year investment
= 1,000 / (1.068)^5
= $719.69
The 5 year investment will have a lower present value and will be charged lower.
Answer:
$192
Explanation:
Calculation for how much FICA-OASDI tax will be withheld from the employee's pay?
FICA-OASDI tax=($117,000-$113,900)*6.2%
FICA-OASDI tax=$3,100*6.2%
FICA-OASDI tax=$192
Therefore how much FICA-OASDI tax will be withheld from the employee's pay is $192
Answer:B. One year from now Bond A's price will be higher than it is today.
Explanation:A Noncallable bond is a bond whose investment cannot be redeemed before its maturity date by the issuer, it can only be redeemed after the payment of a penalty.
The issuer of a noncallable bond makes itself vunerable to interest rate risk mainly because, at the issuance of the bond, it is locked to the interest rate it will pay only when the bond's maturity date is achieved.
Coupon rate is the rate at which a bond repay its owner,it can be annual.
Answer: Individual demand refers to the demand for a good or a service by an individual (or a household). Individual demand comes from the interaction of an individual's desires. Where as an aggregate demand is an economic measurement of the total amount of demand for all finished goods and services produced in an economy. Aggregate demand is expressed as the total amount of money exchanged for those goods and services at a specific price level and point in time.
