10. Was the dollargenerally stronger or weaker in 2009 according to your calculation?
1. 0.70 x(105.3/102.5) = 0.7 x 1.0273 = 0.7191
2. 12.2 x (105.3/110.5) = 12.2 x .9529 = 11.6259
3. B (0.7 /.75) –1 = -6.67%
4. D(1/12.2)/(1/11.8) – 1 = -3.28%
5. 550
6. 360
7. 550/910 =60.44%
8. 360/910 = 39.56
9.(0.70/0.75)(60.44%) + (12.2/11.8)(39.56%) = .5641 + 0.4090 = .9731 = 97.31%
10. weaker,because dollar depreciated by 2.69%.
