solve

A parameter is 4 quantity that influences the output of an equation. Parameters are usually defined as constants, while the value of the variable in the equation can change. For example, the relationship between the value of a British pound () and a U.S. dollar can be modeled by the equation B = kA where Aand Bare variables and kis a constant that is defined by the current exchange rate. In this case, A represents the American dollar and B represents the British pound. Part A: On one day, the exchange rate model might be B = 0.60.4 with the parameter k = 0.60. Under these conditions, an American tourist exchanging US$ 13 would receive | . Round to the nearest hundredth, if necessary. Hint Part B: Under those same conditions, an English tourist exchanging 13 would receive USS . Round to the nearest hundredth, if necessary. Hint Part C: The next day, depending on the world markets, the exchange rate might change, making k = 0.61 and the model B = 0.6LA. In this case, how much would the American tourist with US$ 13 receive in British pounds? Round to the nearest hundredth, if necessary. Answer | |
