Final answer:
The cost per thousand (CPM) for a full-page advertisement costing $6,400 in a magazine with a circulation of 80,000 is $80.00. There was an error in the options provided as the correct answer is not listed.
Step-by-step explanation:
To calculate the cost per thousand (CPM) for advertising in a travel trade magazine, you use the formula:
CPM = (Cost of the Ad / Circulation) x 1,000
In this scenario, the cost of a full-page advertisement is $6,400 and the circulation is 80,000. Plugging those numbers into the formula gives us:
CPM = ($6,400 / 80,000) x 1,000
CPM = (0.08) x 1,000
CPM = $80.00
Therefore, the correct answer is option 2) $80.00 which is not listed in the provided options. It seems there might've been a mistake in the options provided as none of them match the calculated CPM.
