Let us assume the number of text books sold by keller publishing = x
Then
Then number of text books sold by Scholastic books = 4x
The total number of text books sold = 7775
Then
x + 4x = 7775
5x = 7775
x = 1555
Then
The number of text books sold by Scholastic books = 4x
= 4 * 1555
= 6220

I hope the procedure is clear enough for you to understand.
