Answer:
D and E
Step-by-step explanation:
If the old soup recipe called for x mg of sodium per serving, then let's say the new recipe calls for x - 33% * x.
So we have x - 33% * x. Remember that % just means "out of 100", so 33% = 33/100:
x - (33/100)x
Notice that both these terms contain an x so we can distribute that out:
x * [1 - 33/100], which matches E.
We can simplify this further by subtracting 33/100 from 1:
1 - 33/100 = 100/100 - 33/100 = 67/100 = 0.67
Multiply this by x:
0.67 * x = 0.67x, which matches D.
The answers are D and E.
