The correct option is
B 17.99 and 18.99
The given data set is
Each price is increased by 3 dollars.
Hence, the new data set is
16,99, 18.99, 14.99, 17.99, 18.99
For a set with an odd number of values, the median is the middle value of the data set when it is arranged in an ascending or descending order.
Arranging the data set, we get
14.99, 16.99, 17.99, 18.99, 18.99
Median of the data set = 17.99
The mode of the data set is the value or values that occur most often.
Hence, the mode of the data set = 18.99
Hence, the new median and mode of the data set are 17.99 and 18.99.
