Determine the shifts between centralized and decentralized banking before the Civil War and describe the stabilization of the banking system
during the late 1800s.

i'm pretty sure the answer is 60.

you will have $2593.74 in 10 years if you set aside $1,000 at 10%

you will have $9321.91 in 20 years if you set aside $2000 at 8%

you will have $1469.32 in 5 years if you set aside $1000 at 8%

you will have $1296.87 in 10 years if you set aside $500 at 10%

you will have $239.66 in 15 years if you set aside $100 at 6%

you will have $4660.96 in 20 years if you set aside $1000 at 8%

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
