Afb systems is considering a new marketing campaign that will require the addition of a new computer programmer and new software. the programmer will occupy an office in afb's current building and will be paid $8,000 per month. the software license costs $1,000 per month. the rent for the building is $4,000 per month. afb's computer system is always on, so running the new software will not change the current monthly electric bill of $900. the incremental expenses for the new marketing campaign

The incremental expenses include: $8000 per month being programmer's salary, $1000 per month being software license cost.

Explanation:

Incremental cost refers to additional cost of investment. Here, rent for the building will still be paid for even if the software was not purchased. Also, the electric bill of $900 will always be paid even if the investment in software is not done.
