What are the solutions with the work attached?

Andreas Broszio just started as an analyst for Credit Suisse in Zurich, Switzerland. He receives the following quotes for Swiss francs against the dollar for spot, 1-month forward, 3-month forward, and 6-month forward. Spot exchange rate: a. Calculate outright quotes for bid and ask forward rates for 1 month, 3 months, and 6 months, and the number of points bid-ask spread for each forward contract. b. What do you notice about the spread as quotes evolve from spot toward six months? c. Calculate the 6-month Swiss (risk-free) bill rate, using mid rates. Assume the U.S. T-bill rate is 4%
