Adozen eggs for $2.99 or 30 eggs for $8.00?

A dozen for $2.99 costs less per egg

Step-by-step explanation:

$2.99 is essentially $3, so 2.5 dozen (30 eggs) at that price will be 2.5×$3 = $7.50. This is less than $8.00.

The cost per egg is less at the 12 for $2.99 rate.

... $/egg = $2.99/12 ≈ $0.249167 . . . . lowest cost per egg

or

... = $8.00/30 = $0.266667
