Rahj owns a restaurant. He bought 15 kg of chicked at a price of $9 per kg and 15 bags of rice at a price of $4 per bag. He paid with two $100 bills. How much change did he receive?

Answer 1

The cost of chicken is 15 kg × $9/kg = $<<15*9=135>>135.
The cost of rice is 15 bags × $4/bag = $<<15*4=60>>60.
The total cost is $135 + $60 = $<<135+60=195>>195.
Rahj paid with $100 + $100 = $<<100+100=200>>200.
Therefore, he received $200 - $195 = $<<200-195=5>>5 in change. Answer: \boxed{5}.
