Salmon:

OK so the first thing you can use is the process of elimination

Salmon:

Could you answer the questions that I ask you Please

angiesyl:

mk

Salmon:

In the first half of the equation you can see 25 + .05......does the 0.05 represent dollars or cents?

angiesyl:

idk

angiesyl:

oh cents mb

Salmon:

It is ok... If we are using process of elimination then anything that has dollars and shows that the customer is paying per minute in DOLLARS you should immediately know what?

angiesyl:

tha cents dont belong..?

Salmon:

No that dollars Dont belong because we said that the first company charges what per minute?

angiesyl:

ooohh

angiesyl:

ight

Salmon:

Ok now that you have 2 answers crossed off you can look at the 2 left and realize that in the Second half of the equation it states that there is a flat fee of $50 off the bat and How much do they charge per minute?

angiesyl:

tbh idk

angiesyl:

i need the answer lmaoo

Eiwoh2:

That's what she's guiding you to get. Step by step. :)

angiesyl:

lmao ik

Salmon:

minutes are x and the amount per minute would be the number in front of that.....How much does the second company charge per minute?

Salmon:

The second half of the equation is what we are looking at it represents the second company

angiesyl:

im so confused lmao

Salmon:

Ok so we are looking at the second half of the equation which represents the second company ok?

angiesyl:

mk

Salmon:

The whole number is the flat fee the beginning cost for the phone which is what?

angiesyl:

50?

angiesyl:

bro im so dumb

Eiwoh2:

Naw, you just need a little help. We appreciate your guesses!

angiesyl:

T.T

Salmon:

Yes it is 50

Salmon:

so now we know what the flat fee is....lets look at the amount owed per minute.

angiesyl:

i just guessed loll

Eiwoh2:

Great educated guess 👀

Eiwoh2:

Don't put yourself down, you'll learn. ^^

Salmon:

it was a good guess and correct. to remember that kind of thing you should start looking at the whole numbers the number that does not have a variable next to it will be the flat fee.

angiesyl:

ight

Salmon:

and the number that has the variable next to it will be the amount owed per minute remember we are looking at 3 choices here...A, B, and D

Salmon:

Can you tell me what the amount owed per minute is for the second company? (Hint it is the number that has x with it)

angiesyl:

.05

Salmon:

Good Guess but remember this is the Second half of the equation

angiesyl:

im so confused

Salmon:

ok the equation is split into 2 parts got it?

Salmon:

Part A is the First Company and Part B is the Second company. ok?

angiesyl:

mk

Salmon:

Now we are trying to find the cost for the minutes used which is x

Salmon:

In the SECOND HALF what is the number associated with x?

angiesyl:

wdym by second half

Salmon:

After the equal sign

angiesyl:

ohh

Salmon:

ok wo what is the number that is beside x?

Salmon:

*so

angiesyl:

.01

Salmon:

yes so can the answer be B?

angiesyl:

no

Salmon:

Excellent

angiesyl:

oh wait so it D..?

Salmon:

Now look at the choices again we said it can't be B and it can't be C

Salmon:

knowing that the company 2 charges 1 cent per minute we can look at A and do what?

Salmon:

Company 2 charges 50 for flat fee and 1 cent per minute

angiesyl:

ok

Salmon:

what is wrong with A?

Salmon:

Since we said that company 1 charges 1 cent per minute and 50 flat what can we see is incorrect in A

Salmon:

Sorry company 2

angiesyl:

so the answers is d

Salmon:

There you go!

Salmon:

Great Job that is why dont give up....you got this!

angiesyl:

lmao ight
