ANSWER
D. 4 minutes 40 seconds
EXPLANATION
The given data set showing the number of seconds of each song the playlist is:
283,204,198,229,173,230,168,236,215,204
Let the length of the 11th song be x.
Because he wants the mean to be 3 minutes 40 seconds, which is equal to 220 seconds, we write and solve the following equation for x.





We convert 280 seconds to minutes.

The correct choice is D
Area = 299*34 = 10166 ft^2
Cost = 10166 * 11 = $111,826 (answer)
