The decrease was 3.  (from 30 down to 27)

Always calculate the decrease as a percent of the ORIGINAL number.

        3/30  =  0.1

To change a decimal to a percent, move the point 2 places that way ==> .

                 0.1  =  10% .

When you go from 30 to 27, that's a decrease of 10% .

A car has an initial value of $20,000. The value then "depreciates" or decreases by 10% of its initial value each year. Which eq
Elden [556K]

Answer:

D) v = -2,000y + 20,000.

Step-by-step explanation:

The question gives a linear relationship between two quantities.  This means that the relationship between the initial value of the car and the amount it depreciates each year is proportional, or constant.  Since the value of the car decreases by 10% of its initial value each year, then each year the value will decrease by 10% of 20,000 or 0.10 x 20000 = $2,000.  Since we know the value is decreasing each year, this amount would be subtracted from the initial value of $20,000.  So, D) v = -2,000y + 20,000 would be the only equation that represents this scenario.
