A group of 29 campers is going on a field trip. Each car that goes on the trip can take 4 campers. Write an inequality that shows the minimum number of cars that will be sufficient to transport all the campers.

Let \( x \) represent the number of cars needed to transport all 29 campers.

The inequality that shows the minimum number of cars needed is:

\[ x \geq \frac{29}{4} \]
