Question

. The initial cost for Travis and his band to record their first CD was $1500. Each CD will cost $4 to produce.
If they sell their CDs for $10 each, how many must they sell before they make a profit?

Answer 1

10x > 1500 + 4x

6x > 1500

x > 250

Since x cannot equal 250, they must sell 251 CD's before they can make a profit.

Proof:

$1500+4(250)=2500$

$10(250)=2500$

No net profit

$1500+4(251)=2504$

$10(251)=2510$

Net profit of $6
