It's a multiple choice question and my choices are:
(a)More than 12500 Cds must be produced.
(b)12000 CDs must be produced.
(c)Less than 10500 CDs must be produced.
(d)1500 CDs must be produced.

You can put this solution on YOUR website!
Total costs for producing x CDs= .30x + 15000
Total selling price = 1.50x

Profit = selling price - cost
P = 1.50x - (.30x+15000) > 0
1.50x -.30x - 15000 >0
1.20x -15000 >0
1.20x > 15000

Divide both sides by 1.20:
%281.20x%29%2F1.20+%3E+15000%2F1.20
x%3E12500 CDs sold per week to make a profit.
