I set x-3 and 3x-13 equal to each other and then got x equal to 5. So, I believe the correct answer would be C.) 5
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!
