yes

Which steps could be used to solve this story problem? Billy had 20 rubber balls and 12 plastic balls. He shared the balls equally among 4 friends. How many more rubber balls did each friend get than plastic balls? A. Subtract 12 from 16. Then multiply the difference by 4. B. Divide 20 by 4. Divide 12 by 4. Then find the difference between the two quotients. C. Multiply 20 by 4. Multiply 12 by 4. Then find the difference between the two products. D. Subtract 4 from 20. Subtract 4 from 12. Then add the differences together.

OpenStudy (anonymous):

what do u think it is

OpenStudy (radar):

With 20 rubber balls divided among 4 friends, how many are you going to give to each friend?

OpenStudy (anonymous):

5

OpenStudy (anonymous):

i go with b

OpenStudy (radar):

O.K, now how many of the 12 plastic will each of the 4 friends get.

OpenStudy (anonymous):

3

OpenStudy (radar):

B is the way I would go.

Which steps could be used to solve this story problem? Blake took flyers to the shopping center to advertise his car wash event. By the time he arrived 14 of the flyers had blown away. He ended up putting 50 flyers on blue cars, 26 flyers on white cars, and 32 flyers on silver cars. How many flyers did Blake start with? A. Add 50 + 26 + 32. Then subtract 14 from that sum. B. Add 50 + 26 + 32. Then add 14 to that sum. C. Subtract 14 from 50. Then add 26 to the difference. D. Subtract 26 from 50. Then subtract 14 from the difference

OpenStudy (anonymous):

is this one D

OpenStudy (radar):

D that method would say 50 -26 = 24 and then subtract 14 from that would be 10. Does that sound like the amount he started with......10!!

OpenStudy (anonymous):

so the answer is D

OpenStudy (anonymous):

OK I have another one

OpenStudy (anonymous):

can u help

OpenStudy (anonymous):

Which describes the steps that can be used to solve this problem? Kenny bought 4 tickets to the baseball game. Each ticket cost $3. He gave the cashier $20. How much change would Kenny get? A. Calculate the amount of money that 4 tickets cost. Multiply that number by the amount of money Kenny gave the cashier. B. Calculate how much one ticket costs. Multiply that number by the amount of money Kenny gave the cashier. C. Calculate the amount of money that 4 tickets cost. Divide that number by the amount of money Kenny gave the cashier. D. Calculate the amount of money that 4 tickets cost. Subtract that amount from the amount of money Kenny gave the cashier.

OpenStudy (radar):

Do you really think he could start with 10 and lose 14 and put all those left on the cars? Focus ...

OpenStudy (anonymous):

no

OpenStudy (anonymous):

so its not D

OpenStudy (radar):

Obviously it is not D. We are back to the flyers problem!

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

but really i think its B

OpenStudy (radar):

I hope you are not just guessing, because B seems reasonable.

OpenStudy (radar):

On that last one, you better figure that one out, or never go to the mall.

OpenStudy (anonymous):

what do u mean u netter

OpenStudy (anonymous):

i mean u better

OpenStudy (radar):

I mean you need to know when you get back the correct change lol! You don't want to be taken advantage of, do you??

OpenStudy (anonymous):

no not at all hahaha

OpenStudy (radar):

Then what is your choice for that one?

OpenStudy (anonymous):

A?

OpenStudy (anonymous):

right?

OpenStudy (anonymous):

ok i'm confuse which question are we on lost here ?

OpenStudy (anonymous):

take long to write must be long

OpenStudy (radar):

Lets do what A. says and see if you get back the correct change. 4 times cost of tickets is 4 X $3 = $12 Now multiply $12 by $20 giving you $240. is that what you expect to get? 4 tickets and $240 in change for you 20 bucks.........

OpenStudy (anonymous):

right

OpenStudy (radar):

You might like that, but you will wait a long time for that much change lol.

OpenStudy (anonymous):

right

OpenStudy (radar):

A is not a viable choice.

OpenStudy (anonymous):

so

OpenStudy (radar):

I am waiting for your correct answer.

OpenStudy (anonymous):

i got C and i'm not guess you have to find out the change

OpenStudy (anonymous):

this time am i right

OpenStudy (anonymous):

sir......

OpenStudy (anonymous):

is it C

OpenStudy (radar):

Calculate the amount of money that 4 tickets cost. Subtract that amount from the amount of money Kenny gave the cashier. Are we looking at the same problem????

OpenStudy (anonymous):

yes what r u looking at

OpenStudy (radar):

I just posted it again, it is just above your last post

OpenStudy (anonymous):

ok so was i right when i said that its C

OpenStudy (radar):

I think you need to read all of the choices and pick the one that gives you the correct change. Do you know what your change should be?

OpenStudy (anonymous):

yes i pick all so is it D i tried i just dont get it is it D

OpenStudy (anonymous):

is it D

OpenStudy (radar):

Here is what D is saying calculate what the 4 tickets cost......that would be 4 times $3 or $12.00 Now subtract that from what Kenny gave the cashier. He gave him $20.00 so $20.00-$12.00 = $8.00 Is that what you expect to get back in change?

OpenStudy (anonymous):

ok is it D or not

OpenStudy (anonymous):

yes D is right

OpenStudy (radar):

I gotta run. Good luck with your studies. You should know if $8.00 is the correct change or not, if it is the right amount then it is D.

OpenStudy (anonymous):

wait i have 1 more please stay
