Step-by-step explanation:
<span>In the question "Jane Marko buys a car for $43,900.00. In three years, the car depreciates 48% in value. How much is the car worth in three years", the correct answer is $22,828.00 (option A).
The cost of the car = $43,900.00
Depreciation in value in three years = 48% of $43,900.00 = 0.48 x 43,900.00 = $21,072.00
Value of the car after three years = $43,900 - $21,072 = $22,828.00</span>
To solve this problem you must apply the proccedure shown below:
1. You have the following quadratic equation given in the exercise above:
2x²−6x+1=0
2. The quadratic equation is:
x=[-b±√(b²-4ac)]/2a
Where:
a=2
b=-6
c=1
3. When you substitute these values into the quadratic equation, you obtain:
x=3/2-√(7)/2
x=3/2+√(7)/2
