The formula to calculate the amount of money gained after interest with respect to time is the following:
[tex]A=P(1+rt)[/tex]Where "P" is the initial amount, "r" the interest rate in decimal notation, and "t" the time:
Replacing the values:
[tex]A=900(1+(0.06)(2))[/tex]Solving the operations:
[tex]A=1008[/tex]Therefore, after two years Larry will have $1008.
