Answer 1

Do you know where to start?

Answer 2

i dont im sorry

Answer 3

Well, you can start by setting the number of say, $10 bills as x. We know that there is 1 more $20 bill than $10 bill, right? So that means that there is x+1 $20 bills.

Answer 4

With me so far?

Answer 5

yes

Answer 6

So then, we know that the total value of the bills is $50. Thus, the sum of the number of $10 bills (x) times its value (10) and the number of $20 bills (x+1) times its value (20) must equal 50. \[10x+20(x+1)=50\]

Answer 7

Then, you just can solve for x to find the number of each bill she has.
