code to alter 3 cells through range of % reductions and paste dependant cell results

I have a cell which gives the result of a model which is fed by numerous variables. One of which is the price of a product. I'm looking to evaluate the impact of percentage discounts from 1% to 100% without manually changing the price cell each time.

Ideally the code would create an output table of % discount and copy and paste result cell value.

i.e:

1% £10,000
2% £9,990....

This is hard to explain so I have attached a simplified spreadsheet where the cells which need changing are C5:C7 and the result cell is I5.

Many Thanks,
James
