Chelsea Bryan · Answer 1

-7.64%

Step-by-step explanation:

1. Find out how much the car went down in value.

21,330 - 19,700 = 1,630

2. Calculate how much 1% of the original value ($21,330) was. One percent is 1/100, which is. 01 when divided.

21,330 *.01 = 213.3

3. Since we now know 1% is equal to $213.30 we can divide $1,630 by $213.30. Doing this will show us how many 1%s are in 1,630.

1,630/213.30 = 7.64181903

4. There are 7.64181903 1%s in 1,630. Because the car's value went down by 1,630, this also means it went down by 7.64181903% We will round this to the nearest hundredth for simplicity's sake.

7.64181903 → 7.641 one is less than 6 so we will round down → 7.64

5. The car decreased by 7.64% in value. This will be written as - 7.64% because a decrease is negative.
