Two square lots was sold for P2500 per square  meter.  If the smaller area is 3 less than half the  measure of the larger area, what model could  be proposed by the owner to its client?  What will be the new model if 15% was applied  after failure to buy the lots after a month of  transaction?  What is the possible amount for the total area of  the transaction if the total area is 900 square  meters? What is the amount of the lot if purchased after a month?
