Word problems suck, don't they. I always go to the end first and look for the big question they're asking. Take #4:



How many plants were neither petunias nor marigolds? Now we know what to look for. Look for clues in the rest of the problem. First, she bought 40 plants. That's a good start. Then, it says that 20% of the plants were petunias, and 60% were marigolds. From those two numbers, you can see that 80% of the plants were petunias and marigolds (I added 20% + 60%), so you know that 20% are neither petunias nor marigolds (100% - 80%). So now all you have to do is figure out what 20% of 40 is, and you'll have your answer. Make sense? Try to apply that sort of process to all of the questions.
