Abuyer paid $55 comma 68055,680, including the buyer's premium, for a car auction. if the auction adds a 1616% buyer's premium to the sale price of the car, then what was the sale price of the car?

The sale price of the car is $48000.

i) let the sale price of the car be = $x

ii) the premium is given as 16%

  therefore the premium of the car will be equal to = 16% of $x

  the premium of the car will be = $0.16x

iii) therefore total price of car in terms of sale price x  = $x + $0.16x

           therefore total price = $1.16x

iv) total price is given as $55,680

Therefore   $55,680 = $1.16x,    therefore $x = .

Therefore the sale price of the car is $48000.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
