### Instruction:
Mark orders 100 chicken nuggets.  A 20 box of chicken nuggets cost $4.  How much did he pay for the chicken nuggets?

### Response:
He orders 100 nuggets and each box has 20 in it so he orders 100/20 = <<100/20=5>>5 boxes
The cost is $4 per box and he bought 5 boxes so he spent $4*5 = $<<4*5=20>>20 on nuggets
