Question

a certain rail company uses a method called demand pricing for setting the prices of their seats. the price per seat starts at a fixed amount. as the train starts to fill up, the prices gradually increase. a consumer watchdog agency selected a random coach car on a train travelling between new york and philadelphia. they asked each traveler for the price paid for the seat. the following is the result of their survey.

price	frequency	cumulative frequency
$45	17	29
$55	14	43
$70	7	50
$88	5	55
$107	4	59

Explanation:

Assuming the question is "How many passengers were surveyed?" (since the last row of cumulative frequency is 59), here's the solution:

Step1: Identify cumulative frequency

The cumulative frequency in the last row of the table represents the total number of passengers surveyed.

Step2: Read the value

From the table, the last cumulative frequency is 59.

Answer:

59
