Answer:

9

Step-by-step explanation:

Range = Highest Value - Lowest Value

Range of the shoe size in Jacob's family=3

Two people in the family wear shoe size 6.

Since Jacob's size is not 6 and it is 3.

Let Jacob's size =x

The shoe sizes are therefore: 6,6,x

Therefore:

x-6=3

x=3+6=

x=9

Jacob's shoe size is 9.
