A product line should be dropped when a. there will be a positive change in income if the product line is dropped. b. all of these answer choices are correct. c. it has a positive contribution margin. d. it has unavoidable fixed costs.

a. there will be a positive change in income if the product line is dropped

Explanation:

The decision regarding whether a product line should be continued or dropped should take into consideration all the relevant costs and net income before and after dropping such a product line.

While considering costs, unavoidable fixed costs need not be considered as those would be incurred irrespective of the product line getting dropped or continued.

A Product line should be dropped only when it results into a positive change in the net income which means, the net income after dropping such a product line should be more than the net income before dropping.

odd consecutive integers are odd integers that follow each other. they have a difference of 2 between every two numbers. if n is an odd integer, then n, n+2, n+4 and n+6 will be odd consecutive integers. the first number in the pattern is always the variable on its own or in this case, "n". examples.
