Owen made a down payment of $1,600 on a car that was 20% of the total price what was the total price of the car
gtnhenbr [62]
Hey there!

We can set up an equation. Since 20% is said as twenty percent, we can conclude that it says "per-cent", which means "per hundred", like century is a hundred years. That way, we can say that 20% is also written as a decimal of twenty hundredths, because it's per hundred. Thus, we're saying that his down payment, 1,600, is (this is keywording for equals) 20% of (keyword for multiplication) the total price (x). That gives us:

1,600 = .20x

Divide both sides by .20

x = 8,000

Therefore, the cost of the car was 8,000 dollars.

Hope this helps!

DochEvi [55]

That's pretty ill-formatted but the answer is D

ax^2 + bx + c = 0

has roots given by

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Bonus quadratic formulas:

The Shakespeare Quadratic Formulas (2b or -2b) are:

x^2 - 2bx + c \textrm{ has zeros at }x=b \pm \sqrt{b^2-c}

ax^2 - 2bx + c \textrm{ has zeros at }x=\frac 1 a( b \pm \sqrt{b^2-ac})
