Sagot :

The year my money would be at least $1300 is year 6.

In what year would the money be at least $1300?

The formula that can be used to determine the number of years that $100 would have a value of $1300 is:

Number of years =  In(FV / PV) / r

Where:

  • FV = future value
  • PV = present value
  • r = interest rate

In(1300 / 1000) / 0.05

0.2623642645 / 0.05

= 5.2 years

Future value in 5 years = $1000(1.05^5) = $1276.28

Future value in 6 years = $1000(1.05^6) = $1340.10
