Of the land owned by a farmer, 90 percent was cleared for planting. Of the cleared land, 40 percent was planted with soybeans and 50 percent of the cleared land was planted with wheat. If the remaining 720 acres of cleared land was planted with corn, how many acres did the farmer own?

Kudos for a correct solution.
Suppose the total land was 100. Then, 90% of 100 = 90.
Of the 90, 40%(36) of land was used for soyabeans, 50%(45) was for wheat.
