Hey there!
The first thing you need to do is convert your percentage into a decimal. You can do this by dividing your percentage by 100 to give you 0.06. Now, you can use this decimal to solve for your answer.
Start by multiplying your initial amount ($12,000) by 0.06 (the rate of decreased value) to find how much money the motorcycle decreases each year.
12000 Ă— 0.06 = 720
The value of the motorcycle goes down by $720 each year. This means that every month, your motorcycle decreases $60 in value.
You can divide 60 by 12,000 to find the rate per month. This will give you 0.005, which you can multiply by 100 to give you a rate of 0.5% each month.
Hope this helped you out! :-)
