Question

NEED HELP, I'M CONFUSED
The Navarro family uses an average of 225 gallons of water per day, 5 gallons of which goes through the family's water filter. The Navarros' water filter can process 45 gallons before it needs ti be replaced.
After how many days of average water use will the family need to replace their filter?
I JUST NEED HELP WITH A STRATEGY!!!!

Answer 1

5 gallons per day through the filter
filter only 45 gallons
45 divided by 5 = ? days

Answer 2

so 5 gallons per day that goes through the filter,

Answer 3

then the 450 (so you just take off the zero and left with 45) and then you divide that by 5 and that is the answer?

Answer 4

so that would be 9 gallons

Answer 5

yep :)
mmm unless there's a typo in the question?
cuz you mentioned in your comment "450"
but in the question it was just "45"

Answer 6

awe yes that was a typo i am sorry it was supposed to be 450

Answer 7

mmm same idea then...
450 divided by 5

Answer 8

225 gallons a day ( a weeks worth (7) days) and 5 gallons go through the filter to be filtered and then 450 needs to be processed in order for it to be replaced by a new filter right?

Answer 9

yup :)
and 225 is just a random number that you don't need cuz it has nothing to do with the filter

Answer 10

the 450 divided by 5 will leave us with 90 days before it is replaced by a new filter!

Answer 11

yep! :D
