why is this incorrect?

Home Properties is developing a subdivision that includes 310 home lots. The 230 lots in the Canyon section are below a ridge and do not have views of the neighboring canyons and hills; the 80 lots in the Hilltop section offer unobstructed views. The expected selling price for each Canyon lot is $55,000 and for each Hilltop lot is $108,000. The developer acquired the land for $2,400,000 and spent another $1,300,000 on street and utilities improvements. Assign the joint land and improvement costs of $3,700,000 to the Canyon section and the Hilltop section using the value basis of allocation. (Do not round your intermediate calculations.) Answer is complete but not entirely correct.
