hey,
your question,
The value of Sanjay’s $21000 car goes down by $2000 every year .Use an equation to determine when his car will become worthless (that is, When it has a value of $0).
If we let y represent the number of years since Sanjay purchased his car, then: 21000 – 2000 y = 0
Step-by-step explanation:
=> 21000-2000y = 0 => 2000y-21000 = 0
=> 2000y = 21000
=> y = 10.5
Therefore, after 10.5 year his car become worthless.
