37 Let be inflation rate and e_f be a percent change in the value of the foreign currency relative to the dollar. According to the text, an equation of the real dollar/euro exchange rate (q) is:

		q = (1 + )/[(1 + $)(1 + ef)]
		q = (1 + $)/[(1 + )(1 + ef)]
		q = (1 + $)(1 + ef)/(1 + )
		q = (1 + )(1 + ef)/(1 + $)
