Choice B would reach 12 dollars the fastest because if you increase 8 by 10% that's 8.80 for week one. Then 10% again is 9.68. 10% again is about $ 10.45. 10% again is about $11.50. Finally another 10% increase is about $12.64. So in total that would be 5 weeks. Plan A would take 40 weeks. Plan C is 8 weeks and plan D is 16 weeks.
