So you would set this problem up as 10 x 9 x 8 x 7, since none of the digits can be repeated. There are 5,040 4 digit passcodes possible.
Let's thing
949 ----- 100% of the price
499 ------ x% of the price
Multiply in cross
949.x = 100.499
949x = 49900
x = 49900/949
x = 52,58%
So, rounding it 52,58% ≈ 53%
Alternative B

Step-by-step explanation:
The others answers would be either too big or too small to fit
<span>1) Find an equation of the plane. The plane that passes through the point (2, 3, 4) and contains the line x = 4t, y = 2 + t, z = 3 − t 2) Find an equation of the plane. The plane that passes through (6, 0, −3) and contains the line x = 2 − 4t, y = 1 + 5t, z = 2 + 2t 3) Find an equation of the plane. The plane that passes through the point (1, −1, 1) and contains the line with symmetric equations x = 2y = 5z 4) Find the point at which the line intersects the given plane. x = 2 − t, y = 1 + t, z = 3t; x − y + 5z = 14 5) Find the point at which the line intersects the given plane. x = 2 + 2t, y = 3t, z = 4 − 2t; x + 2y − z + 2 = 0 6) Find the point at which the line intersects the given plane. x = y − 2 = 2z; 2x − y + 2z = 2</span>
