Answer :
Answer: The number $1 bills is 8 and the number of $5 bills is 8.
Step-by-step explanation:
Let x denotes $1 bills and y be denotes $5 bills.
Then , we have the following equations :-
[tex]x+y=13-------(1)\\\\x+5y=33-------(2)[/tex]
Subtracting equation (1) from (2), we get
[tex]4y=33-13=20\\\\\Rightarrow y=\dfrac{20}[4}=5[/tex]
Substitute y=5 in equation(1), we get
[tex]x+5=13\\\\\Rightarrow\ x=13-5=8[/tex]
Hence, the number $1 bills is 8 and the number of $5 bills is 8.
