I think you would probably put 4 dollars in the bank and have it quadruple each week for 3 weeks because the equation would be 4x4x3 which is 16x3 which is 48. If you did 3 dollars in the bank and have it triple each week for 4 weeks the equation would be 3x3x4 which is 9x4 which is 36. So, again, I think it’s better to have 4 dollars in the bank and have it quadruple each week for 3 weeks
