The Miller family bought 3 crates of eggs last week. Each crate had 18 eggs. Since then, they have eaten 27 of the eggs. How many eggs are left?

The Miller family initially had 3 crates x 18 eggs/crate = 54 eggs.

After eating 27 eggs, they have 54 eggs - 27 eggs = 27 eggs left.

Thus, there are 27 eggs left.
