Fv1 = the future value of cash (in dollars) one year into the future
Fv2 = the future value of cash (in dollars) two years into the future
Fv3 = the future value of cash (in dollars) three years into the future

Pv1 = present value of cash that corresponds to the future value value Fv1
Pv2 = present value of cash that corresponds to the future value value Fv2
Pv3 = present value of cash that corresponds to the future value value Fv3

We'll use the formula
FV = PV*(1+r)^t
where we compound the money annually (n = 1). If the compounding amount is different, then let me know.

Solve for the present value PV to get
FV = PV*(1+r)^t
PV = FV/[ (1+r)^t ]

We'll use that formula to compute the present values for each given future value. The given future values are:
Fv1 = 200
Fv2 = 350
Fv3 = 400

The time values are respectively t1 = 1, t2 = 2, t3 = 3. The interest rate is held constant at r = 9% = 9/100 = 0.09 (we'll use the decimal form for r).

So,
PV = FV/[ (1+r)^t ]
Pv1 = Fv1/[ (1+r)^(t1) ]
Pv1 = 200/[ (1+0.09)^(1) ]
Pv1 = 183.48623853211
Pv1 = 183.49

and,
PV = FV/[ (1+r)^t ]
Pv2 = Fv2/[ (1+r)^(t2) ]
Pv2 = 350/[ (1+0.09)^(2) ]
Pv2 = 294.587997643296
Pv2 = 294.59

and finally,
PV = FV/[ (1+r)^t ]
Pv3 = Fv3/[ (1+r)^(t3) ]
Pv3 = 400/[ (1+0.09)^(3) ]
Pv3 = 308.873392024426
Pv3 = 308.87

Now add up the present values (Pv1 through Pv3) to get
Pv1 + Pv2 + Pv3 = 183.49+294.59+308.87
Pv1 + Pv2 + Pv3 = 786.95

The sum of the present values is 786.95 dollars
