add the numbers on both side by 3
4 + 3 = 7
8 + 3 = 11
rewrite the expression
7<11
that is still true
do the same by multiplying it by 2 and rewrite the inequality
Greetings!
An item at full price is 100%, or by using the percentage formula: 
If something is at 30% off, that means it is 70% of the original price (because minus the percentage from the 100%)
So by substituting the numbers into the percentage formula you end up with:
which is 0.7
So your answer would be D, 0.7!
Hope this helps!
I'll help. I love helping people
