The price per organic egg is 50 cents. The price of a tray of eggs that contains 30 eggs is $12. How much can you save, in cents, per egg if you buy a tray versus individual eggs? Let's answer step by step:
The price per egg in a tray is $12 / 30 eggs = $0.4 / egg. The equivalent of $0.4 in cents is $0.4 x 100 cents / dollar = 40 cents. Hence, you can save 50 cents - 40 cents = 10 cents per egg if you buy a tray. The answer: 10.
