A quadratic equation has the standard form:

ax^2 + bx + c = 0

in the given equation,
a = 3
b = -10
c = 5

plug these values into the quadratic formula.

(-b +/- sqrt(b^2 - 4ac)) / (2a)

(-(-10) +/- sqrt((-10)^2 - 4(3)(5)) / (2*3)
(10 +/- sqrt(100 - 60)) / (6)
(10 +/- sqrt(40)) /6

bulgar [2K]

Answer:

Step 1: $15

Step 2: 38%

Step-by-step explanation:

Step 1:

40 - 25 =15.

Therefore, the price would decrease by $15.

Step 2:

40 multiplied by .38 equals 24.80. You would round that up to 25. If you plugged in 37%, it would equal 25.20, which is over the price. Therefore the price decreased by 38%.
