maddy1251 · Answer

Do you know which variables to apply to what numbers And can you define Independent variables vs. Dependent variables?

maddy1251 · Answer

I will help you with this, as long as you work along with me. If you do not know something, I will explain to you, okay?

Adrienne had a party at a local skating rink. She spent one hundred dollars for a party room and eight dollars per person for skates. Let c be the total cost of the room and skates, and let f be the number of friends at her party. Write an equation to represent the problem. Which is the independent variable? Explain
c=total cost
f=number of friends at the party.
100+8f=c
This is the equation we have to help solve.

a variable (often denoted by x ) whose variation does not depend on that of another.

maddy1251 · Answer

a variable (often denoted by y ) whose value depends on that of another.

swaugh · Answer

i dont get it

maddy1251 · Answer

'c', the cost would be your dependent variable, because it depends on 100 and 8f

maddy1251 · Answer

Your 'f' variable should be the independent variable.

maddy1251 · Answer

That number controls what c will be, since 100 is already given and paid for.

swaugh · Answer

i still dont under stand it

maddy1251 · Answer

What don't you understand?

swaugh · Answer

oh nvm i didnt read it correctly

maddy1251 · Answer

Does everything make sense then?

swaugh · Answer

yes f is the independent variable because it doesnt rely on 100 and 8f

maddy1251 · Answer

Well, 8f is part of 'f' but you basically got the right idea.
In a way, you could say that 'f' is the independent because thats the variable we can control. Basically when you throw the party, you control how many people you want to come. But you cannot control the cost.

swaugh · Answer

so the answer is "'f' is the independent because thats the variable we can control"

maddy1251 · Answer

Yep.

maddy1251 · Answer

We can 'manipulate' it.
