Do not post the same quesiton multiple times. It wastes everyone's time.
The cost of erecting a building is $1,000,000 for the first floor, $1,100,000 for the second floor, $1,200,000 for the third floor and so on. If the lot and the other initial costs are $5,000,000 and each floor produces $200,000 annual income how many floors should be built to maximize profit for the first 10 years?
