please help !!
Brandon and his band want to record a CD of their music. The recording studio charges $750.00 for the session and $3 for each CD. The studio requires that bands spend a minimum amount of $1200.


a) Write an equation for the cost of the CD’s in relation to the number of CD’s.


b) Write and solve an equation or inequality that can be used to determine the minimum number of CD’s they would need to buy if they only want to spend the minimum amount.


c) The band decides to buy 200 CD’s, how much money will they be spending? They are planning on selling them to recoup their expenses at the recording studio as well as make a little profit. What is a reasonable amount of money they should charge for each CD? At that price, how many CD’s will they have to sell to recoup their expenses?


d) If the band sells all the CD’s at that price, what is the total profit that the band will make (after expenses)?
