You purchase a piece of equipment for $440K at the beginning of the year (Jan 1, 2020). Calculate the tax impact of disposing the equipment on Jan 1, 2024 for either $80,000 or $100,000. Assume a CCA rate of 30% and a tax rate of 20%. The equipment is the only asset in the class. Only use the half-year rule for the first year (not in year of disposal).
