Question

A camping ground began with 240 pounds of food and each day consumed about 12 pounds. After how many days did they have 180 pounds left

Answer 1

If you take 240 divided by 12 = 20
Then take 180 divided by 12 = 15
Take 20-15=5 after 5 days they had 180lbs left

Answer 2

Answer:

5 days

Step-by-step explanation:

Set up linear equation; food= 240-12(day) f=240-12d

f(1)=240-12(1)=240-12=228

f(2)=240-12(2)=240-24=216

Now set food to equal 180, solve for days:

180=240-12d

-240  -240

-60=-12d

/-12  /-12

5=d

To check: f(5)=240-12(5)=240-60=180
