Answer:
Step-by-step explanation:
If it has to be done as a proportion, set it up as 112/12 = x/3
In other words, "112 cents is to 12 eggs, as x cents is to 3 eggs."
So your proportion is 112/12 = x/3.
Cross-multiply to get 12x = 336, then divide both sides by 12 to get:
x = 28 cents (per 3 eggs.)
The other way to think about it is, since 3 is one quarter of a dozen, the price of 3 eggs should be one quarter the price of 12.
112 cents divided by 4 is 28 cents.
Hope this helps!
