Jaycob will need 13 bags. To elaborate: one bag of fertilizer covers an area of 33 ft²; for a total of 400 ft², Jaycob needs 12.12 bags. Verifying this calculation, 400 divided by 33 equals roughly 12.12 bags when rounded to two decimal places. Since he cannot purchase a fraction of a bag, he needs to buy 13 bags in total to adequately cover his lawn.
It's not as complex as others have suggested; the problem states the number of bags needed, and since he can't buy a fraction of a bag, he rounds up to 13 bags. Hope this helps and enjoy your day!
