Answer:
$28
Step-by-step explanation:
The website charges 20%, so Macy receives 80%.
Then:
80% x 35=.8 x 35=28 ....................
A polynomial with roots a and b is (x - a)(x - b).
(x - 2)(x - (-1))(x - 4) = 0
(x - 2)(x + 1)(x - 4) = 0
has roots 2, -1, and 4.
4/3 = 320/x
4x = 320*3
4x = 960
x = 240
Check:
320/240 divide both by 80
= 4/3 :)
