what does x represent?

I don't know. That is confusing me.

cost of large latte? medium? or small?

Can we assume that x=6?

where are you getting that?

nvm

S = cost of small
M = cost of medium
L = cost of large

`a large latte costs 2 dollars more than a medium latte`
so L = M+2
agreed?

yes

S = x
M = x + 2
L = 2 + (x + 2) or 4 + x

the next step is to plug S = x/6 into 5(S+4) + 7(S+2)

so we are learning about plugging in numbers. can we work around that level?

you mean replacing S with some number like 7?

yeah

how would you get to the answer? each answer has an x in it

so can we like plug in 7 for x?

I am really confused on this.

Do you see how I got 5(S+4) + 7(S+2) ?

yes

12x/6 + 34

12x/6 simplifies to ???

2x

THANK YOU!!!

so 2x+34 is the answer

I have another question

b = 4d? is that a typo?

Yes sorry \[b = 4d^2\]

and a = 2x + 3 is correct? or no?

that's correct

I don't see how to connect a and b. They have no variables in common

i have checked with many numbers none of which seems to work

something seems missing

i will check on that with my teacher. thank you :)
