If i have 150,000 crystals, and one costume cost 4,000 crystals, how many costumes can i buy total? * explain yes this is school related.

Okay, think of it this way: 

You have to find how many times 4,000 goes into 150,000. 

This will tell you how many costumes you can buy.

To make this easier, we can divide 4 by 150. (this is proportional to 4,000 and 150,000 since we took 3 zeros from each number; you will get the same answer) 

150/4= 37.5 

You can buy 37 whole costumes.

Hope this helped! 

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer
