When acquired in $2016,$ the tractor$/$trailer rig cost $$585,000$ and was expected to remain in service for eight years, or $1,500,000$ kilometres. Estimated residual value was $$60,000.$ The truck was driven $150,000$ kilometres in $2014,195,000$ kilometres in $2018,$ and $235,000$ kilometres in $2019.$ After $100,000$ kilometres in $2020,$ the company traded in the Mack truck for a Freightliner rig with a fair market value of $$510,000$ on August $15.$ Triad Freight paid cash of $$40,000.$ This trade$-$in will bring in significantly more income to Triad Freight by reducing operating costs.
