A sporting goods store purchased a snowboard and marked it up 25% from the original cost of $120. Then, wanting to make room for
Margaret [11]

The price after the discount was $45.

When the sporting goods store bought the snowboard and marked it up by 25%, the price became:

<em>= Original cost x ( 1 + markup percentage)</em>

= 120 x ( 1 + 25%)

= 120 x 1.25

= $150

The snowboard was then discounted by 70%, the new price becomes:

<em>= Current price x ( 1 - discount rate)</em>

= 150 x ( 1 - 70%)

= 150 x 30%

= $45

In conclusion, the price after the discount was $45.

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:
x= \frac{11+- \sqrt{121-4(2)(15)} }{2(2)} \\  \\ &#10;x= \frac{11+-1}{4} \\  \\ &#10;x=3, x= 2.5

So, the correct answer to this question are option B and D
