Investing $1,500,000 in TQM's Channel Support Systems initiative will at a minimum increase demand for your products 1.5% in this and in all future rounds. Last year's sales were $150,000,000. Assuming similar sales next year, the 1.5% increase in demand will provide $2,250,000 of additional revenue. With the overall contribution margin of 32.1%, after direct costs this revenue will add $722,250 to the bottom line. For simplicity, assume that the demand increase and margins will remain at last year's levels.

a) 32 months

b) 25 months
