The value of Maggie's car decreased by 25% since last year, when she bought it. If the car is now worth $15,000.00, how much was the car worth when she bought it

$11.250

Step-by-step explanation:

Percentage of Decrease = 25%

To know the cost of the car when she bought it, we must first know the amount of depreciation. After that, we then subtract the value from the new price.

Therefore:

25% of $15,000

= 25 / 100 * $15,000

= 0.25 * $15,000

= $3750.00

The value of the percentage of Decrease is $3750.00.

To know the worth of the car when she bought it:

$15,000.00 - $3750.00

= $11.250.

The worth of the car when she bought is $11.250

the car was worth $20000 when she bought it.

Step-by-step explanation:

Let x represent the worth of the car when she bought.

The value of Maggie's car decreased by 25% since last year, when she bought it. It means that the amount by which it decreased is

25/100 × x = 0.25x

The value of the car after the loss in value would be

x - 0.25x = 0.75x

If the car is now worth $15,000.00, it means that

0.75x = 15000

x = 15000/0.75

x = $20000

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
