Determine LN
Since LM is a bisector, then we have:
(See attachment for illustration)

Collect Like Terms


Solve for w


LN is calculated as thus:

Substitute 4 for w



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
Answer is: 111.847
Method:
1 m/s = 2.23693629 mi/hr
Therefore ->
50 (m/s) * 2.23693629 (mi/hr) = 111.847 mi/hr
