Compute the percent change needed to return to the original value after percent off (or on).
Determine the percent change needed to "undo" an initial percent change. Has a plot function as well. If an amount of $100 has 20% added, what percent do we need to drop it by to return to the original value?
fin_percent(20) yields $100 increased by 20% = $120 (Percent to reverse = -17%)
fin_percent(percent, value = 100, symbol = "$", digits = 2, plot = TRUE)
| percent | Change in percent (enter 10 for 10%, not 0.1) | 
| value | Principal | 
| symbol | value units (default = "$") | 
| digits | Rounding of results (default 2 places) | 
| plot | Whether to plot the result (default TRUE) |
