That would  a set of 5 numbers in ascending order with  4 being the middle one and the other 4 being the highest possible So it is
2, 3, 4, 9, 10
Mean is 28/5  = 5.6 answer
( I am assuming that each number is different)
Of duplicates is allowed then its 4 4 4 10 10  whose mean is 6.4

<span>Given
data:
12 square feet of paper at 1 dollars per square feet
=> 12 square feet * 1 dollar = 12 dollars
4 feet of wood at 3 dollars per foot
=> 4 feet of wood * 3 dollars = 12 dollars
14 yards of string for 2 dollars per yard
=> 14 yards of string * 2 dollars = 28 dollars
Now let’s solve that total:
=> 12 dollars + 12 dollars + 28 dollars
=> 52 dollars.
Thus, Maria spent a total of 52 dollars in buying her need supplies.</span>
