ok so you need to find when the value is zero because when it is completely depreciate it is worthless eg value is zero

so $$0=-105t+735$$

anonymous · Answer

subtract 735 from both sides$$-735=-105t$$

anonymous · Answer

anonymous · Answer

divide both sides by -105 and you get t is $$\frac{ -735 }{ -105 }=t$$$$7=t$$
