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?
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}.
To find out how much change Rahj received, we need to calculate the total cost of chicken and rice, and then subtract it from the amount he paid with the two $100 bills.
1. Calculate the cost of chicken:
Price per kg of chicken = $9
Quantity of chicken bought = 15 kg
Cost of chicken = Price per kg × Quantity of chicken bought
= $9/kg × 15 kg
= $135
2. Calculate the cost of rice:
Price per bag of rice = $4
Quantity of rice bags bought = 15 bags
Cost of rice = Price per bag × Quantity of rice bags bought
= $4/bag × 15 bags
= $60
3. Calculate the total cost:
Total cost = Cost of chicken + Cost of rice
= $135 + $60
= $195
4. Calculate the change received:
Total amount paid = 2 × $100
= $200 (since two $100 bills were used)
Change received = Total amount paid - Total cost
= $200 - $195
= $5
Therefore, Rahj received $5 as change.
