A band wants to create a CD of their last concert. To create the CD's, the cost will be $350 advertisement fee plus $3 per CD. Write an inequality that represents how many CD's they can buy with maximum of $1225. Solve the inequality

So they can't spend more than 1225 dollars which means the inequality starts off with 1225 > X

Then you know there will be a minimum of 350 dollars if they use it, followed by how many CDs they want times their cost (3 dollars)

The final equation would be 1225 > 3X + 350
