Rhonda bought 3.9 kg of coffee, which is equivalent to 3900 grams.

To find out how much she spent on coffee, we need to first calculate the price per gram of coffee:
Price per gram = $15.99 / 780 grams
Price per gram = $0.0205 per gram

Now, we can calculate how much Rhonda spent on 3900 grams of coffee:
Amount spent = 3900 grams * $0.0205 per gram
Amount spent = $79.95

Therefore, Rhonda spent $79.95 on coffee.
