If the value of a machine depreciates 15percent every year.What was its value 1 year ago.its present value is 85000

(1-.15)x = 85,000

Solve for x.

2500

To find the value of the machine one year ago, you need to calculate 15% of its present value and subtract that from its present value. Here's how you can do that:

Step 1: Calculate the depreciation amount.
15% of 85000 = 0.15 * 85000 = 12750

Step 2: Subtract the depreciation amount from the present value.
85000 - 12750 = 72250

Therefore, the value of the machine one year ago was $72,250.
