Quinn mailed four postcards that each cost 0 point 2 5 dollars , five letters that each cost 0 point 4 4 dollars , two large envelopes that each cost 0 point 8 0 dollars , and one small package for 5 point 1 0 dollars Which cost on the list of mailing fees on Quinn’s receipt would skew the mean?

The small package cost $5.10, while all the other mailing fees are between $0.25 and $0.80. Because $5.10 is much larger than the other costs, it is an outlier that pulls the mean upward and would skew it. The correct choice is the cost of the small package.
