That depends on how long he spends in the hospital - taking that much antacid with make digestion nearly impossible. :-)

Answer 2

Do you know how many is in a gross? If not, just google it.

Answer 3

Answer 4

Google is amazing. Anytime you don't completely understand a word or phrase, google it. Once you understand all the words, the question will become much easier.

Answer 5

so 144 in one gross.............

Answer 6

And consuming 3 bottles a day. How many days will 144 bottles last?

Answer 7

If I have 24 ounces of water and I drink 1 ounce per minute, how many minutes will it take me to drink all the water?

Answer 8

432?

Answer 9

How did you get that?

Answer 10

whoa nvm i 144x3

Answer 11

Now, you got it. :-)

Answer 12

i was right???? @gypsy1274

Answer 13

Almost, but do the calculation to see if it makes sense.

Answer 14

ill try.. hmmm then if i dont get it can you get back on me pls? @gypsy1274

Answer 15

multiplication and division are opposite operations. Sometimes they can be reversed as easily as someone who is dyslexic reverses b's and d's.

Answer 16

I'll get an alert as soon as you respond so if I'm still online - I'll check back.

Answer 17

@gypsy1274 is it B.?

Answer 18

How did you get that answer?

Answer 19

You were close with 144 * 3, with one small mistake.

Answer 20

i dont get it cuz it didnt say how many days... he just uses 3 bottles every day but, how many days? @gypsy1274

Answer 21

He starts with 144 bottles and uses 3 bottles each day. The problem is asking you to figure out how many days.
To put it another way...if you were to add 3 many times over, how many times would you add 3 (starting with 0) to get to 144 or what times 3 = 144?

Answer 22

oh i thought the 144 is the gross inside the bottle or something... i didnt know it was talking about 144 bottles..so D.48?

Answer 23

Yes. That is the correct answer.

Answer 24

thank you ^_^ @gypsy1274 thanks for helping me step by step

Answer 25

No problem. The question is, do you really understand what you have done here?
I can write another problem to help you learn it if you want.

Answer 26

@gypsy1274 yes please

Answer 27

If I have 24 ounces of water and I drink 1 ounce per minute, how many minutes will it take me to drink all the water?

Answer 28

Or, if your driving 100 miles per hour (your speed demon! Watch out for cops!) and you want to go 1500 miles, how long will it take you to get there?

Answer 29

haha iight i need time lol calm down XD @gypsy1274

Answer 30

first one is 24 mins right? and the 2nd one is...wait

Answer 31

Glad I could brighten your day.
Yes to the first answer. That question was inspired by my water bottle. :-)

Answer 32

lol funny @gypsy1274 .. what a nice bottle you got there hahaha

Answer 33

OK speed demon, how long will it take you to get where you are going?

Answer 34

900 mins? @gypsy1274

Answer 35

That is correct. I was expecting the answer in hours since I gave you the speed in miles per hour. While your answer is correct, changing the units like that will cause you to lose points on these standardized exams.

Answer 36

well so how many hours?:<
and yeay im KINDA right :D @gypsy1274

Answer 37

In the days before the latest round of state tests, my nephew said "I'm off to school, where they beat the imagination out of you!" He is not wrong. All this standardization kills creativity.

Answer 38

You are correct. Not kind of correct. You understand the problem, you just converted it to minutes. Now convert it back to hours.

Answer 39

@gypsy1274 haha true :D

Answer 40

Or even easier, distance divided by rate = time

Answer 41

thatll take forever haha how...

Answer 42

oh that....

Answer 43

minutes divided by 60 = hours because there are 60 minutes in an hour.

Answer 44

15 hours?

Answer 45

Yes. Do you feel like you understand, or would you like to do more?

Answer 46

You can always find practice math problems on Khan Academy - www.khanacademy.org -> If you want, I could be your coach on there. It's free, just like this site. and a great supplement to school instruction (just like here.) It never hurts to have more resources.
