creditcard

Credit Card Simulator - Explore the effects of different choices 

Use the following commands with the input bar to specify your parameters:

previousbalance=<desired #> eg: previousbalance=400
i = <desired decimal form annual interest rate> eg: i=0.195

to alter the items on the credit card, use the following
item1 = <new name of item 1> eg: item1="Purchase: Mobile Phone"
*Note spaces do not show up properly in the table unless you use /; to indicate a space, so for example if I want to say:
"Purchase: Mobile Phone"
I should type: item1="Purchase: \; Mobile \; Phone"
Use the same syntax to alter items 2 through 4

To alter the prices of these items, use
charge1=<desired charge> eg: charge1=99.99
charge2, charge3, and charge4 will change the other values

If any of the sliders have restriced the values you wish you change you can right click the slider to set a new maximum and minimum.

If you prefer to alter the new balance directly, you can type
newbalance=<desired#>
If you want to restore the new balance to being the sum of the charges and the previous balance as it was when the sheet loaded, type
newbalance= Sum[charges]+p
