10 The price of a second-hand car is $6975. Which of the three offers on the right is the best offer?
$900 reduction, 15% discount, pay just seven eights
Give a reason for your answer.

15%

it is the best because it is the option that offers the lowest price

Step-by-step explanation:

900 reduction : 6975 - 900 = 6075

15% discount :

0.15 x 6975 = $1046.25

 6975 - $1046.25 = 5928.75

7/8 x 6975 = 6103.13

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
