Answer:
62.5
Step-by-step explanation:
1. convert percent value to decimal
30.00/100=.3
2. turn problem into equation where x equals the original price
x*.3=18.75
3. solve
(x*.3=18.750)/.3
x=62.5
Both A and B will be answers to the solution.
Since you already have the equation set and equal to 0, you can find the roots by first getting your a, b, and c values for the quadratic equation.
a = 1 (number attached to the x^2)
b = -3 (number attached to the x)
c = 5 (number not attached to a variable)
Then we can use these values in the quadratic equation.
