First, let's convert the kilograms to grams using a conversion factor so that we have everything in the same unit:
Now, to find how many bags there will be, you simply have to divide the total amount of cinnamon by the amount that there will be in each bag:
The whole number (52) represents the quantity of bags, and the decimals that follow represent the cinnamon left over that isn't enough to fill one more bag.
I think about 52 bags 2 kilometers = 2,000 grams 2, 000/ 38 = 52. repeated decimal(which would be the amount leftover) I believe the answer would be 52 bags.
431.2+826.4d=2910.4 431.2 is only the first day therefore it doesn't need the variable because the variable represents the number of days. 826.4 even says "each remaining day" referring to what the variable represents.
