Cassie wants to sell her car before it drops below a value of $4,000. She purchased the car for $22,000 and knows the value depreciates by $3,600 each year.

(( Help with writing an inequality that represents the # of years it will take before Cassie's car is worth less than $4,000 ))

I think what you would do is subtract the "salvage value" of 4,000 from 22,000 to get 18,000. Then since you need the number of years, you would divide 22,000 by the depreciation price of 3,600 to get 5. It would take 5 years for the car's value to reach 4000, therefore she would want to sell it before then.
