If you put down 15% on a $9000 car and pay monthly payments of $189.40 for 48 months , what is the total price of the car?

The total amount payable for the car if you put a down 15% on a $9000 car and payment of $189.40 for 48 months will be:
Amount=(15/100×9000)+(189.40×48)
=1350+9091.2
=10,441.2
The total amount of money paid for the car after a period of time will be $10,441.2

She would have to walk 12+24 which is 36 but she only has to walk:
√12²+24² = 26.8

36-26.8=9.2

She saves 9.2 ft

Hope this helps :)
