To find the discount %, we must use the equation below.
Discounted Price / Original Price = 1 - Discount %
15.05 / 21.5 = 1 - Discount %
Subtract 15.05 / 21.5 from both sides and add Discount % to both sides to get the following equation.
Discount % = 1 - 15.05 / 21.5 = 1 - 0.7 = 0.3 = 30% discounted

Very simple!
We are given a concave spherical mirror with the following dimensions:
Radius = 60 cm; D o = 30 cm
Height = 6 cm; h o = 6 cm
First, we need to know the focal length, f, of the object (this should be given). Then we can use the following formulas for calculation:
Assume f = 10 cm
1/ f = 1 /d o + 1 / d i
1 / 10 = 1 / 30 + 1 / d i
d i = 15 cm
Then, calculate for h i:
h i / h o = - d i / d o
h i / 6 = - 15 / 30
h i = - 3 cm
Therefore, the distance of the object from the mirror is 3 centimeters. The negative sign means it is "inverted".
