I hope someone can shed some light on this question in my workbook. It is a holiday week and I can ask my teacher until tuesday - I'm going mad.
You buy 12 dollars worth of apples. They are kind of small so the cashier gives you two extra for free. This reduces the price per dozen by exactly 1 dollar. How many apples did you get for 12 dollars?
ok, I know the answer in the back of the book says 18 apples, but how??
any help much appreciated
