Answer:
$342 is to be divided into $100 bill, 10 bills, and $1 bills.
We can distribute 342 as :
300 + 40 + 2
300 can be made by 3 $100 bills as [tex]3\times100=300[/tex]
40 can be made by 4 $10 bills as [tex]4\times10=40[/tex]
2 can be made by 2 $1 bills as [tex]2\times1=2[/tex]
So, you can see that you need 3 $100 bills, 4 $10 bills and 2 $1 bills.
