John Jones has 1,100 acres, 700 in cropland valued at $2,300 each and 400 in pasture valued at $1,500 each. 350 acres of pasture could be converted to cropland at a total cost of $70,000. The remaining 50 acres would subsequently decline in value to $500 each. Calculate the value of the total acreage before improvements. Calculate the value of the total acreage after improvements. Are improvements financially feasible in this case?
