Question

If eight trash bags last for thirty days then how many trash bags do you need for 180 days

Answer 1

Let's Just See How Many Times 30 Goes Into 180


`(180)/(30) = 6`
Since 8 trash bags last 30 days, let's multiply


`6 * 8 = 48 \: bags`
ANSWER

You'll Need 48 Trash Bags For 180 Days

Answer 2

Set up the proportion. Then cross multiply and isolate the variable to solve.

`(8(trash bags))/(30 (days)) = (x (trash bags))/(180 (days))`

8(180)= 30(x)

`(8(180))/(30) = (30x)/(30)`

8(6) = x

48 = x

Answer: 48 trash bags
