Hi!
In any quadratic in the form you have given (), the discriminant is ALWAYS
Given the quadratic formula:
<u>-------------------------------------------------------------------------------------------------------------</u>
The discriminant would be the part of the equation that is under the square root.
<u>-------------------------------------------------------------------------------------------------------------</u>
Therefore, your answer is
To find the price after the discount the equation would be 39..98x.30which would equal 11.99. subtract that from the price before the discount and you get $27.99. thats your first answer. to find the second answer you would do 23.99 divided by 11.99 (the diacount from the first equation) to get the discount rate of 2% so your final answers are $27.99 and 2%
