1. Internet: $80, with no sales tax, plus $10 shipping fee --> 80+10=90;
2. Store X: $90, a 10% discount, plus 10% tax on discounted price --> 90*0.9*1.1=89.1
3. Store Y: $90, no tax --> 90;
4. Store Z: $90, a 10% sales tax, and $10 rebate after tax --> 90*1.1-10=89.
So the lowest price is $89.

An easy question i suppose could have taken max upto a minute to solve
Lowest price comes out to be 89
from Store Z: $90, a 10% sales tax, and $10 rebate after tax
which is 10% of 90 = 9 hence price + Sales tax = 90 +9 =99$
99$ - 10$ = 89$
