Problema Solution
Rocky but 9 similar notebooks she gave the Kush you $10 and receive change of 5.05 what was the cost of one notebook
Answer provided by our tutors
The problem statement is ambiguous... we assume that 'but 9 similar notebooks' is intended to mean '9 similar notebooks were purchased'. Let 'x' represent the cost of a notebook, then 9 are purchased with $5.05 change:
10=5.05+9x
x=0.55
So each notebook would cost 55 cents, $0.55.
