Q$22$: Your name is Angela. You work as the CFO of a British company that deals extensively with companies in Nigeria. You know that you will need to buy $2,590$ mio NNA $($Nigerian Naira and mio means million$)$ in exactly $3$ months from now in connection with a business deal you have done with a Nigerian company. Nigeria is a major oil producer and the value of the Nigerian Naira fluctuates a lot $--$ especially when the price of oil changes. In short, Angela's company needs a currency hedge involving NNA versus British pound $($GBP$).$

Angela calls three banks, National Bank of Lagos $($NBL$),$ Barclays and Citibank, and asks for quotes on the number of NNA per GBP$.$ The following quotes are made by the three banks:

NNA per GBP $($bid$-$ask$)$

First, Angela needs $($you need!$)$ to decide which bank to optimally trade with $--$ but she learnt how to do this in her International Financial Management course at ODU!

How many GBP does Angela's company need to pay the bank in $3$ months from now for the currency hedge?

Give your answer in GBP to the nearest pound.
