Question

one dozen eggs cost 1.98$. How much does 1 egg cost? ( round to the nearest cent )

Answer 1

it would be .16 cents

Answer 2

If 1 dozen eggs (12 eggs) cost $1.98, then you need to divide $1.98 by 12 to find how much 1 egg costs. 
So, $1.98 divided by 12 = .165  There is a 5 so you would round it up to 17 cents.
