i think
Well if 100%= $8.05
then to find 10% you divide by 100.
10%=$0.85
You would then take this off of your original price. This is how I like to lay mine out:
100%=$8.05
- 10%=$0.85
= 90%=$7.20
Therefore 90% of $8.05 is $7.20
Circumference= 2pi radius

x⁴ + x = 0
x(x³) + x(1) = 0
x(x³ + 1) = 0
x = 0 or x³ + 1 = 0
- 1 - 1
x³ = -1
x = -1
