Donny decides to manufacture and sell his band's CD. It requires an investment of $5916 for computer hardware and it will cost $4.55 for materials for each disk. If each CD sells for $14.75, how many must he sell to break even?
Let
x ------> number of CD
we have
5,916+4.55x=14.75x --------> linear equation that represent this situation
Solve for x
14.75x-4.55x=5,916
10.2x=5,916
x=580
therefore
