Evarado paid $1.12 for a dozen eggs at his local grocery store.  Determine the cost of 3 eggs
Anton [14]
First you have to find out the cost for a single egg.

Since there are a dozen (12) eggs, you can divide the total cost by that.
1.12/12 ≈ 0.09.

Using the base cost of an egg, you can find out how much 3 eggs would cost.

0.09 x 3 = $0.27
