In 2018, Mark purchased vacant land for $30,000. In 2022, Mark sold a three-year option, for $2,000, to Janet to purchase the land for $100,000. The land was valued at $80,000 at that time. In 2024, Janet exercised the option and purchased the land at the $100,000 option price when the property was worth $250,000. Assuming the land was capital property, what would be the amount of the taxable capital gain to Mark in 2024 if Mark has no other capital gains in the year?
