soldi70 [24.7K]

Answer:

a) equilibrium price to rise, fall, or stay the same and equilibrium quantity to rise.

Explanation:

Substitute goods are goods that can be used in place of each other.

If the price of rice rises, consumers shift to the consumption of potatoes. Price and quantity demanded of potatoes increases

The bumper harvest increases supply of potatoes. Price falls and quantity increases.

The effect on equilibrium quantity of potatoes would be indeterminate but equilibrium quantity would rise.

A bond with a face value of $1,000 has 10 years until maturity, carries a coupon rate of 8.6%, and sells for $1,140. Interest is
nordsb [41]

Answer:

Price of bond=948.8583731

Explanation:

<em>The value of the bond is the present value(PV) of the future cash receipts expected from the bond. The value is equal to present values of interest payment plus the redemption value (RV). </em>

Value of Bond = PV of interest + PV of RV

Semi-annual interest = 8.6% × 1,000 × 1/2 =43

Semi-annual yield = 9.4%/2=4.7 %

<em>PV of interest payment</em>

PV = A  (1- (1+r)^(-n))/r

A- 43, r-0.047, n- 20

= 43× (1-(1.047)^(-10)/0.047)

= 549.7724893

<em>PV of redemption Value</em>

PV = F × (1+r)^(-n)

F-1000, r-0.047, n- 20

PV = 1,000 ×   1.047^(-20)

PV = 399.0858837

Price of Bond

549.772 + 399.085

=948.8583731
