Answer: y = 1.2</h3>
Work Shown:
Inverse variation equations can be written in the form x*y = k for some fixed number k. Let's plug in the first point (x,y) = (1.6, 6) to compute the value of k
x*y = k
1.6*6 = k
9.6 = k
k = 9.6
Therefore the equation updates to
x*y = 9.6
Plug in x = 8 and solve for y
x*y = 9.6
8*y = 9.6
y = 9.6/8 .... divide both sides by 8
y = 1.2
Y=4(0-2)^2-1
y=15
(0,15)
plug 0 for x
0=4(x-2)^2-1
(5/2,0) and (3/2,0)
plug 0 for y

First find what one percent is. Then multiply it by 15 (your markup). Then add it to your original price.
