Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Mandy has three $20 bills while Manny has two $50 bills. If both of them decide to exchange their bills for $10 bills, how many more $10 bills than Mandy will Manny have?

### Response:
Three $20 bills amount to $20 x 3 = $<<20*3=60>>60.
So, Mandy will have $60/$10 = <<60/10=6>>6 $10 bills.
Two $50 bills amount to $50 x 2 = $100.
So, Manny will have $100/$10 = <<100/10=10>>10 $10 bills.
Hence, Manny will have 10 - 6 = <<10-6=4>>4 more $10 bills than Mandy.
