Conditional Formatting greater than 100%

[henro8]

In a job workbook, Row 51 is to be filled with reimbursable expenses every month, beginning in Column E and continuing through Z.
The numbers that are entered in that row need to be marked up 10%.
Is it possible to format the row in such a way that each number entered in each cell is automatically marked up 110%, or multiplied by 1.1? thanks in advance.
