The image shows a blackboard with text written in French. The text on the board reads:

"22.90 € pour 12 achats 
19.90 € pour 11 achats"

This translates to:

"22.90 euros for 12 purchases
19.90 euros for 11 purchases"

The text is displayed in two columns, with the first column listing the price for 12 purchases at 22.90 euros and the second column listing the price for 11 purchases at 19.90 euros.
