How do you know if a word problem question is asking for simple interest or compound interest?

Question

P.s. I already know the formula and what both of them mean

Answer 1

the problem will tell you which it is. Although, if it neglects to say the compounding period, it is most likely simple interest.

Answer 2

Is there any key words that I should remember for each of them

Answer 3

yeah - compound or simple!

Answer 4

Is there any other key words bc the teacher like to go hard and they never say compound or simple.
