Answer :
We can use proportion here. As we know, cost of a rocker is now 80% of original.
So:
[tex]159.95$------------------80%
[/tex] crossmultiplying
[tex]x---------------------------100%[/tex]
[tex]x= \frac{159.95*100}{80}=199.94[/tex] - aswer
So:
[tex]159.95$------------------80%
[/tex] crossmultiplying
[tex]x---------------------------100%[/tex]
[tex]x= \frac{159.95*100}{80}=199.94[/tex] - aswer
