Sipho buys peanut in a bulk at r5/kg and sells them in 100g packets for r1 each. his aunt owns a packaging business and supplies sipho with free packets, for packaging the peanuts .(write sipho's rate per 100g packet.

Sipho buys 1 kg of peanuts at R 5. This means that for 1000 grams (1000 grams is equivalent to 1 kg) Sipho is paying R 5.
