Answer:
b. 1,062.81
Explanation:
the key to answer this question is to remember that valuation of a bond depends basically of calculating the present value of a series of cash flows, so let´s think about a bond as if you were a lender so you will get interest by the money you lend (coupon) and at the end of n years you will get back the money you lend at the beginnin (principal), so applying math we have the bond value given by:

where: principal as said before is the value lended, coupon is the rate of interest paid, i is the interest rate and n is the number of periods
so applying to this particular exercise, as it is not said we will assume that 6% and 7% are interest rate convertible seminually, so the price of the bond will be:

price=1,062.81
take into account that here we are asked about semianually payments, so in 8 years there are 16 semesters.
The above situation is an example of shoe leather cost of inflation.
A shoe-leather cost is what people pay when they frequently visit the bank to withdraw cash to use to pay for products in the wake of intense inflationary pressure. The term "shoe-leather cost" symbolizes all costs, including time spent, bank fees, brokerage fees and transportation costs.
High inflation discourages people from keeping large sums of cash on hand because the value of money rapidly depreciates during this time. More money is kept in banks by them. Additionally, repeated price increases force people to constantly withdraw money for transactional needs. Due to this, they frequently visit their bank to withdraw cash in order to pay for goods and services. These frequent journeys degrade their shoe leather, resulting in a 'shoe-leather cost.'

<span>When a monopolist switches from charging a single price to perfect price discrimination, it reduces the consumer surplus. Consumer surplus is defined as the difference between what a consumer believes they should pay for a good or service and the total amount that they actually do pay. The amount they pay is known as the market price and what they are willing to pay is noted on the demand curve. </span>
