"The price reported is a weighted average."

A weighted average is a way of calculating an overall number when some items matter more than others by giving each item a different level of importance, or weight. Investors use weighted averages to combine figures like prices, returns or earnings so the result reflects the size or significance of each part — like grading a class where a final exam counts more than a quiz, producing a score that better represents true performance.
