If a car costs $10,000 and decreases in value by 5%, what is the new value?

To find the new value of the car after a 5% decrease, use the formula:

[ \text{New Value} = \text{Original Value} - (\text{Original Value} \times \text{Percentage Decrease}) ]

Substituting the values gives:

[ \text{New Value} = $10,000 - ($10,000 \times 0.05) = $10,000 - $500 = $9,500 ]

The new value of the car is $9,500 after the 5% decrease.
