Answer: Standard Price is $26.30 and the range is $21.80
To find the average, you have to multiply the mean by 5 to find the combined total. The total is $103. Then, subtract away the prices of the other 4 hotels. This will give you $26.30 left for the Night-Time Rest Days.
To find the range, subtract the lowest value of $11.20 from the highest value of $33.
