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