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
