how many passengers paid a fare at or

Explanation:

Response

The question seems to be incomplete (the full question about "at or" what price is missing). But assuming we need to find cumulative frequency for a certain price, for example, if we want to find how many passengers paid at or below a certain price, we use the cumulative frequency column.

If we assume the question is "How many passengers paid a fare at or below $55$", we can use the cumulative frequency for the price $55$.

Step1: Identify the cumulative frequency for $55$

From the table, for the price $55$, the cumulative frequency is given as $43$.

(Note: If the actual question was different, for example, "at or below $70$", the cumulative frequency for $70$ is $50$, etc. Since the question is cut off, but based on the table, if we take a common question, let's assume it's about a price where we can use the cumulative frequency. Let's proceed with the example of $55$ as a likely candidate.)

Answer:

If the question is about fare at or below $55$, the number of passengers is $43$. (If the actual price in the full question is different, use the corresponding cumulative frequency from the table. For example, for $70$ it's $50$, for $88$ it's $55$, for $107$ it's $59$, for $45$ it's $29$, for $39$ it's $12$.)
