In a certain shop, notebooks that normally sell for 59 cents each are on sale at 2 for 99 cents. How much can be saved by purchasing 10 dollars of these notebooks at the sale price?
I don't understand:
- either notebooks normally sell 59 cents, each one is sold at 2 (amount) for 99 cents,
- or if we sell 2 of them, price for them is 99 cents?
