This sentence is incorrect because it is a run-on sentence. This means that it should be broken into two separate sentences: 
Ladybugs are also called lady beetles. In Europe, they are called ladybird beetles. 
It's easy to catch this mistake by either reading the sentence out loud and listening for a natural pause, or by looking for one subject and one verb per sentence (Ladybugs are; they are).

Answer:$412.75
Explanation:
If they up sell by 27% you would need to take the original price of $325 and find 27% of that. To do this, multiply 325x.27 (.27 is 27% converted to a decimal) which is = to 87.75 you then need to add $87.75 to $325 which will get you $412.75.
