Three deposits are made: the first deposit of $200 today (or time 0), the second deposit of $300 one year from today, and the third deposit of $400 four years from today. If the accumulated value of the three payments is $1,200 five years from today, find the dollar-weighted rate of return (assume compound interest). Set up an equation and indicate the method you used (calculator, website, successive approximation) to solve your equation
