RE: (11C) Solve for [i] given [n] [PMT] [FV]
This update solve for [i] with either group of three known variables.
[n] [PMT] [PV]
[n] [PMT] [FV]

LBL A [n]
LBL B Reset
LBL C [PMT]
LBL D [PV]
LBL E [FV]

Procedure: To solve [i]
input [n] [PMT] [PV] > GSB 1 (answer [i])
input [n] [PMT] [FV] > GSB 2 (answer [i])

Example:
36 > A > 36 ( input [n] )
360 > C > 360 ( input [PMT] )
360000 > E > 360000 ( input *[FV] )
*GSB > 2 > 14.94 ( Answer [i] )

36 > A > 36 ( input [n] )
360 > C > 360 ( input [PMT] )
1000 > D > 1000 ( input *[PV] )
*GSB > 1 > 36 ( Answer [i] )
