Answer:
48%
Step-by-step explanation:
let's say the initial price of an item is $100
if you take 40% off then you pay only $60
now if you take 20% off 60 you pay $48
$48 is 48% of 100
We have to put values of domain to find range

![\\ \ast\sf\longmapsto D_R=[-1,0,1]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20D_R%3D%5B-1%2C0%2C1%5D)



Now
![\\ \ast\sf\longmapsto R_R=[-2,1,13]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20R_R%3D%5B-2%2C1%2C13%5D)
