You can put this solution on YOUR website!
x= number of candies in a full bag.
I see two ways of attacking the problem:

You can see this as a problem of proportions:
30%2F100=6%2Fx-->x=6%2A100%2F30=highlight%2820%29

You can remember what percentages mean. Percentages are fractions and can be written as decimals.
30% = 30%2F100=3%2F10=0.3
To calculate 30% of some amount you calculate 3/10 of that amount, by multiplying the amount times 3/10 or 0.3.
0.3x=6-->x=6%2F0.3=highlight%2820%29

NOTE:
If your teacher objects to two or more equal signs in one math sentence, just pretend I wrote
30% = 30%2F100 --> 30% = 0.3 and
0.3x=6-->x=6%2F0.3-->x=highlight%2820%29
