Explanation:

Let the number Sara was thinking about be x

halving the number to get an answer = 38.5 can be expressed as

1/2 X = 38.5

The equation with x in the information can be written as

1/2 x = 38.5

solving it becomes

1/2 x= 38.5

x = 38.5 x 2

x=77

The number Sara was thinking about = 77
