Write in algebraic form a calculation of U.K pounds per euro that uses U.S. dollars per U.K pound (FRED code: EXUSUK) and U.S. dollars per euro (FRED code: EXUSEU). Then plot since 1999 the exchange rate of U.K. pounds per euro using these two U.S. dollar exchange rates. Select “Add Data Series” again, choose the “Line 1” button, and then type in the code for the U.S. dollar-pound exchange rate (FRED code: EXUSUK). Type in “a/b” (without the quotes) at the Formula box and then set 1999-01-01 as the initial date for the “Observation Date Range.” Select “Redraw Graph.”)
