Sounds like a homework assignment to me.

Assume the terms are 2%/10, net 30. If your invoice is $100, you can pay $98
after ten days, or $100 after 30. So you want to know: "What rate of interest
turns $98 into $100 after 20 days?" Feed those numbers into Rate, as in:

=rate(20/365,0,98,-100)

please?


Thank you
