Solve the equation of the function for n.
a(n) = 3n - 20
a = 3n - 20
a + 20 = 3n
(a + 20)/3 = n
n = (a + 20)/3
n(a) = (a + 20)/3

Since they reduced the markup price, or higher price, by 10%, the new markup price is 20% over the manufacturer price.
Answer:
f(x)could also be written as y in y= mx+ c
by taking two points we are gonna calculate.
(0,1), (4,-1)
finding m
y*- y'/x*-x'
=1-(-1)/0-4
=2/-4
=-2
now c ( intercept)
take any point
eg. (0,1)
y=mx+c
1=-2×0+c
1=c
equation then equals to
y=-2x+1
f (x) =-2x+1
