Step 2: Key in the equation and store it in a variable TVM.
Key in
the equation for TVM.
CJ [I) 1 G SPPV .CD 0 PMT 0
1000 I [B PV 0 G FV 0 SPPV
I ENTER I
Create the variable TVM.
CJ TVM I STO I
The USER menu shows a new label for TVM.
Step 3: Make TVM the current equation.
Key in the name TVM.
CJ TVM
Store the name TVM in the variable EQ.

Step 4: Use the Solver to calculate any of the five variables n, i, pmt,
pv, or tv, for given values of the other four variables.
Select
the Solver menu.
SOlVR
All the variables in TVM and SPPV appear in the menu. (The vari-
ables in
SPPV appear because the current equation, TVM, contains
SPPY.)
Given values N = 30 x 12, I = 11.5/12, PMT = -630, and FV =
0, calculate PY. (PMT has a negative value because money paid out is
a
negative number, while money received is a positive number.)
