a. If she can sing at each wedding but decides to maximise profits, she will only sing at the weddings of those paying her $200 as it is the higher of the two payment options. 
Should she sing at the $200 customer weddings, she would make;
= 20 people * $200
= $4,000
b. Price Discrimination is the charging of different types of customers different prices for the same or similar goods. 
If your friend knows how to perfectly charge the two different groups the different prices that they value her at then she will be able to attend and sing at both weddings making her revenue;

= 1,000 + 4,000
= $5,000

Explanation:
a. If interest rates decrease over the period of investment, Treasury bond prices will increase. Thus, Dudley Savings Bank should take a long position in the futures contracts on the Treasury bonds. As T-bond prices go up, so will T-bond futures prices.
b. Given a long position:
Net profit = Sale price of futures − Purchase price of futures
= $107,687.50 − $107,312.50 = $375.00
Purchase price of futures = 107 − 100 = 107 10/32% × $100,000 = $107,312.50
Sale price of futures = 107 − 220 = 107 22/32% × $100,000 = $107,687.50
