Final answer:
The scale of measurement for the cost of a ticket is Ratio scale, which allows for calculating ratios and has a definite ordering and a starting point.
Step-by-step explanation:
The scale of measurement for the cost of a ticket is Ratio scale.
The ratio scale is the highest level of measurement, which means it has a definite ordering and a starting point, and ratios can be calculated. In the case of the cost of a ticket, it has a starting point of $0, and we can compare the prices of different tickets and calculate the ratio between them.
For example, if one ticket costs $10 and another ticket costs $20, we can say that the second ticket is twice as expensive as the first ticket.
