Question

A bag of fertilizer covers 33 square feet of lawn. ​ Jaycob’s 400 square foot lawn will require 12.12 bags of fertilizer. Since Jaycob cannot buy 0.12 of a​ bag, how many bags of fertilizer should he​ buy?

Answer 1

Answer:

13 bags

Step-by-step explanation:

1 bag of fertilizer covers 33 ft² of lawn

Jaycob's 400 ft² will require 12.12 bags

Let's see if its correct...

$\frac{400 ft^2}{33ft^2}$ × 1 bag = 12.12121212 bags

Or 12.12 bags(rounded up to two decimal places) . Its correct!

But  since Jaycob cannot buy 12.12 - 12 = 0.12 bags of fertilizer, he will have to buy 13 bags of fertilizer in order to cover the whole lawn.
