Answer 1

im only looking at this question because of one direction and why arent you constantly replaying soml?

Answer 2

lol and what?

Answer 3

i love soml and i am!

Answer 4

the indepedent variable is the $100 for a party room because that is a fixed number, the skates is dependent on the number of people attending.

Answer 5

can you write the equation please and i was thinking the independent variable would be f

Answer 6

C=8f +100

Answer 7

Independent variable is the # of friends, f.

Answer 8

100 is the constant.

Answer 9

regardless of how many friends that come, there's a constant charge of $100.

Answer 10

so the independent variable is f and what is the equation?

Answer 11

C = 8f + 100

Answer 12

why would it be f though can you explain. @Easyaspi314

Answer 13

C is the cost of the party. The cost, C, depends on the # of friends, f, show up at the party. So C depends on f. So C is called the dependent variable, and C, depends on f. f, the # of friends is the independent variable, as it doesnt depend on anything.

Answer 14

Thank you
