Well let's talk about the first one. If 8 quarts costs $5.44 how would you find the cost of 1 quart?

- anonymous

Oh, ok. U do 5.44/8

- anonymous

0.68?

- Mertsj

|dw:1359427317441:dw|

- Mertsj

yep. .68

- anonymous

Do you know how to do the chart?

- Mertsj

For the skittles...if 20 ounces cost 3.79 how much does 1 ounce cost.
I think you do the chart by filling it in for the various products.

- anonymous

Um. I got a really long decimal for that one.

- anonymous

0.1825

- Mertsj

It says you can complete the chart OR use a proportion.

- Mertsj

That would be 18 1/4 cents per ounce

- anonymous

My teacher said she wanted both, but okay :)

- anonymous

18 1/4? mk

- anonymous

done.

- Mertsj

I'm not sure what she wants in the chart. Didn't she do an example in class?

- anonymous

no. ;/ Ill ask tomorrow; thats ok.

- Mertsj

ok

- anonymous

we can do the proportion part for now.

- Mertsj

ok. Do you know how to do those?

- anonymous

i think, but for the spring water one i get a long decimal

- Mertsj

Yes. It comes out to be .119166666 I think I would round that to $.12 per bottle

- anonymous

oh,ok,tnx

- Mertsj

yw

- anonymous

wanna help with the others? u don't have to if u don't want to

- anonymous

:0 99 smart score :0

- Mertsj

I can check your answers if you want.

- anonymous

mk. let me work them out really quick

- anonymous

hmm. i get a long decimal both ways.

- anonymous

how do you decide what goes on the numerator/denominator?

- Mertsj

.239583333 rounds to how many cents per card?

- anonymous

um.. .20?

- Mertsj

When it say per card or per bottle or per rose you know that goes on the bottom.

- Mertsj

.239 is more than 23 cents but less than 24 cents but it is closer to 24 cents.

- anonymous

oh; so \[\frac{ 5.75 }{ 24 }\]

- anonymous

?

- Mertsj

Yes, for the valentine cards.

- anonymous

oh, ok

- anonymous

oh. let me see. so, 23 cents per card,yes?

- anonymous

i mean dollars

- Mertsj

.239 is closer to .24 so round to .24 which is $.24 or 24 cents

- anonymous

\[\frac{ 29.99 }{ 12 } = \frac{ ? }{ 1 } ?\]

- Mertsj

Yes.

- anonymous

it is asking $ _____________ per card

- Mertsj

then put .24

- anonymous

oh. zero dollars and 24 cents.ok

- Mertsj

yes

- anonymous

I wrote it. Thanks.

- Mertsj

yw

- anonymous

For the second one, can u look at the equation i typed

- Mertsj

That was the correct equation for the rose.

- anonymous

great! let me work it out.

- anonymous

2.49, yes?

- Mertsj

You seem to have a little trouble with the rounding. Did you get 2.499166666?

- anonymous

yes sir.

- Mertsj

Is 2.499 closer to 2.49 or 2.50?

- anonymous

2.50

- Mertsj

Then you should put 2.50 per rose

- anonymous

Okay, sorry. I am not the best at math,

- Mertsj

Not a problem. You will learn.

- anonymous

thanks for helping me and putting up with me. give me a second to write that down

- anonymous

Okedokey.

- Mertsj

ok

- anonymous

next is the better buy.

- anonymous

let me attempt it.

- Mertsj

Yes, the hangers. ok

- anonymous

so, A is .12.

- Mertsj

yes

- anonymous

B is 0.149.

- Mertsj

yes

- anonymous

C is .1325

- anonymous

So Id guess A is the better buy?

- Mertsj

Clearly

- anonymous

ok. 1 sec

- anonymous

done

- Mertsj

Good. Which is the better vitamin buy?

- anonymous

let me see.

- anonymous

one minute.

- anonymous

almost done

- anonymous

A is 0.03

- Mertsj

yes

- anonymous

B is 0.0299

- Mertsj

Yes. Which is a tiny bit cheaper than A

- anonymous

Really?

- anonymous

I would've thought A was the cheapest.

- Mertsj

.0299 is less than .0300

- anonymous

nvm no

- anonymous

its 1 dollar
b is just cents

- anonymous

And c is....

- anonymous

0.0216, so C is the cheapest

- Mertsj

Yes. Very good.

- anonymous

thank you,sir

- anonymous

now,the next problem...ummm

- anonymous

Hmmm

- Mertsj

Yes. It gives you the time in hours and minutes and then it asks for miles per hour.

- anonymous

How much is 45 mins of an hour?

- Mertsj

How much of an hour is 15 minutes? (Think of the clock face...)

- anonymous

Hm.... One minute,

- anonymous

3/4 of an hr

- Mertsj

Very good.

- anonymous

And 3/4 is 0.75

- Mertsj

yes

- anonymous

\[\frac{ 0.75 }{ 2.25 } = \frac{ ? }{ 1}\]

- anonymous

?

- Mertsj

Just a minute 3 hours and 45 minutes is 3.75 hours and you are trying to find miles per hour so hours should go on the bottom.

- Mertsj

And it's 225 miles NOT 2.25

- anonymous

oh, yes, typo, i apologize.

- Mertsj

\[\frac{225miles}{3.75 hours}\]

- anonymous

60 miles per hr?

- Mertsj

yes

- anonymous

great, tnx

- anonymous

now the map.

- Mertsj

yes

- Mertsj

centimeters PER mile

- anonymous

yes, so \[\frac{ miles }{ centimeters}\]

- Mertsj

The word after PER goes on the bottom

- anonymous

oh ok. sorry, i get those mixed up/

- Mertsj

\[centimeters per mile = \frac{centimeters}{miles}\]

- anonymous

1.3 cm per one mile?

- Mertsj

Yes. Actually it is 1.333 which is 1 and 1/3. She might want the exact answer this time. You could put both perhaps.

- anonymous

Oh,alright. Will do.

- anonymous

one moment.

- anonymous

mk. now the other one.

- anonymous

it says to fill in the table.

- Mertsj

But first it wants to know how many miles PER gallon his car gets.

- anonymous

So, a multiple step problem. shall I attempt it?

- Mertsj

Just figure out first how many miles per gallon his car gets.

- anonymous

let me try it really quick

- anonymous

hm...

- Mertsj

56 miles per 2 gallons

- anonymous

he gets 56 miles per gallpm

- Mertsj

No. He gets 56 miles on 2 gallons

- anonymous

oops. yes.
i did 168-224

- anonymous

got 56

- Mertsj

Look at the first column of the table. It tells you that he goes 56 miles on 2 gallons of gas. How far would he go on 1 gallon of gas?

- anonymous

so, 56,112,168,224,280,356

- anonymous

?

- Mertsj

\[\frac{56 miles}{2 gallons}=\frac{x miles}{1 gallon}\]

- anonymous

so, 56,112,168,224,280,356
Could I fill that in?

- anonymous

Or no?

- Mertsj

Based on the table, how
many miles per gallon does Rolando's car get?

- Mertsj

That is the first question the problem asks. You need to answer it.
