By taking a foreign language, students increase their vocabulary by 140 percent. If those who do not take a foreign language know 3640 words, how many words do the foreign language students know?

Here's how I solved it: 3640 x 240/100 = 8736 words

correct?

    I did it this way, considering that 100% = 3640 of how many words people without a second language have, and now you know you need to get 40% more, you times 3640 by .4 to get1456 which is the 40%. Now you just add that too the 3640 from earlier and get 5095.

    Hope this helps

    I believe that it correct. an "increase [of] 140%" is 100% + 140% of the original value.
