Bulk rice is on special at $0.75 per kilogram. Pam scooped some rice into a bag and put it on the scale. How much will she pay for 820 g of rice?
Since bulk rice is sold at $0.75 per kilogram, that would mean it costs 0.75/1000 = $<<0.75/1000=0.00075>>0.00075 per gram.
Therefore, Pam would pay 820 x 0.00075 = $0.615. Answer: \boxed{0.615}.
