This is very simple if you think about it. Ill explain it without confusing your mind with mathematical jargon, because I understand you looked this up for a reason. 

You have to use your choices for this. 

A: 6
B: 28
C: 32
D:34


Keep those numbers in mind.


She uses a total of 38 Bills.

Lets think of the first letter choice.

Letter Choice A:

If she uses 6 five-dollar bills ($30) she still needs to pay $190 more.

She would need 19 ten-dollar bills to pay this.

But then she would only have used 25 bills in total. It is stated she used 38.


Letter Choice B:

If she uses 28 five-dollar bills ($140) she still needs to pay $80 more.

She would need 8 ten-dollar bills to pay this.

But then she would only have used 36 bills in total. It is stated she used 38.



Letter Choice C:

If she uses 32 five-dollar bills ($160) she still needs to pay $60 more.

She would need 6 ten-dollar bills to pay this.

That would make it so that she used 38 bills, making this our answer.
