Answer:
A. 500
Explanation:
We know that it can't be B. or C. since it has to be greater than 150, so (I know this isn't the way to do it) bet is you try multiplying your leftover answers you have by .3 you would see that 200 times .3 is 60, so that isn't it but 500 times .3 is 150!
I hope this helps and you have a great day! :)
