Question

One dozen eggs cost $1.98. How much does one egg cost ?

Answer 1

$1.98 per 12
$\frac{x}{1.98}= \frac{1}{12}$
1.98*1=12*x
$\frac{1.98}{12} = x$
x= 0.165
x=0.17

Answer 2

We know that there is 12 in one dozen so all we do is divide $1.98 by 12 and get the unit price which is .165 cents per egg.
