A bank teller handed an equal number of $100 notes and $20 notes to Samantha.
Samantha used 13 pieces of $100 notes to buy a television and 25 pieces of $20 to buy a plane ticket.
In the end, the ratio of the remaining $100 notes to the remaining $20 notes became 7 : 3.
What amount of money did the bank teller give Samantha?
