Larsen Realty Corporation purchased a tract of unimproved land for $51,000. This land was improved and subdivided into building lots at an additional cost of $28,000. These building lots were all of the same size but owing to differences in location were offered for sale at different prices as follow.

Group		No. of Lots		Price per Lot
1		8		$4,950
2		15		6,600
3		21		3,300

Operating expenses for the year allocated to this project total $15,700. Lots unsold at the year-end were as follows.

Group 1		4 lots
Group 2		6 lots
Group 3		2 lots

At the end of the fiscal year Larsen Realty Corporation instructs you to arrive at the net income realized on this operation to date. (Round ratios for computational purposes to 1 decimal place, e.g 78.7% and final answers to 0 decimal places, e.g. $5,845.)

I keep getting stuck on this, I'm not sure what I am doing wrong. I answers keep ranging in the 25000 area. Any assistance is greatly appreciated
