FB 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. What are the incremental expenses for the new marketing campaign?
