Question

three years ago alice paid $7400 for a car. she just sold it for $6500. What is the percent of decrease

Answer 1

Hi Haylee, it's 12.16%.  Here is how:

 

 

7400 - 6500   =  12.16%

      7400

 

 

You can see that 7400 is the original value and 6500 is current value.  The difference of two prices is the lost value from the original value.  To find out the percentage for lost value, you must put lost (difference or how much it has changed) value (7400-6500 = 900) on top and divide by original (total) value to see the percent of decrease.

 

To check it, multiply (12.16%) and 7400 to get 900.

 

I hope you understand how I did it.

 

Good luck to you.
