Mr. nelson sold 147 bags of popcorn and 216 bottles of water in 3 days. at this rate, how many more bottles of water than bags of popcorn will mr. nelson sell in 5 days?

Mr Nelson will sell 115 more bottles of water than popcorn. First, you find the rate of popcorn and water being sold. That will be 147 bags divided by 3 and 216 bottles divided by 3. You get 49 bags and 72 bottles. You subtract those two numbers, 72-49=23. 23 is the number more waters sold than the popcorn. Finally, you multiply 23 by 5 days and you get 115. So it's 115 more waters sold than popcorn.

I’m not sure about that

Understanding what? lol
