Hillary was scuba diving. She was 30 feet below the surface when she swam toward the dive platform. She dropped her camera when she was 10 feet from the surface and had to swim down 15 feet to get it. At what elevation did Hillary retrieve her camera?

A diagram can help to see this situation better. First we have the surface and 30 feet bellow is where she was at the beginning:
