Answer:
<u>$467.05</u>
Step-by-step explanation:
The price is $562
First, 20% off of that:
562 - 20% of 562 = 562 - 0.2(562) = $449.60
Second, he has to pay 6% tax on this amount, so:
6% = 6/100 = 0.06
449.60 + 0.06*449.60 = $476.58
He won't be paying this amount, because paying through credit card will give him 2% discount on this, so:
476.58 - 0.02(476.58) = <u>$467.05</u>
<u></u>
<u>Final Price: $467.05</u>
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
The first answer is G. The next one is B.
