A sample of 86 motels is selected from a large urban area and the price for a night of lodging for a single room was

determined for each motel. The mean rate is computed to be $91 and the standard deviation is $15. One motel
charged $57 per night which is the 15th percentile. Another motel charged $116 per night which is the 75th
percentile.

How many motels charged at least $57 per night? Round your answer to the nearest integer.
