Alright this is the last time i'll ask for help with math I promise (i answered some of the questions for you) johnathan and his band want to record and sell CDs. The recording studio charges an initial set-up fee of $250, and it charges $6.00 to burn each CD.

a. Define the variables in this situation. (Picture below - the first two is already done for you)

b. Complete the table to explore this relationship. (Picture below - already done)

c. use the table to write an algebraic rule that describes the relationship between the variables in the problem situation (C = -6n + 250)

here are the problems i didn't

d. explain whether an input value of 54.5 makes sense in the context of the problem situation.

e. what are the domain and range of this situation and what do the domain and range represent?

f. create a graph for this problem situation. Be sure to scale and label your axes. (Im not sure what you can do for this one: either draw it or explain how the graph would look like.)

that's all I need help with (if it's too much that's fine!, don't answer this! ^^)
