A piece of machinery depreciates $6000 the first year, $5300 the second year, and $4600 the third year. If the
rate of depreciation is constant, what is the amount of
depreciation of the piece of machinery in the sixth year?

$2500

Step-by-step explanation:

Each year the number goes down by $700 dollars, so you can just keep subtracting $700 for each year until you get to the sixth year. Or, since there are 3 years until the sixth year, you can multiply 700×3 and subtract $2100 from $4600.
