You need to find the number of papers that
Booby delivered for Betty
In words:
( total amount that Bobby made ) / ( 10 cents / paper ) = number of papers he delivered
papers delivered
---------------------------------
Now what is Betty's pay for delivering the papers?
cents
-------------------------
Now what is the difference:
( Betty's pay ) - ( what she paid Bobby )

Betty gets to keep $11.70 for the day
( notice that I did all calculations in cents until
the end when I converted to dollars )
