An electronics store makes a profit of $61 for every standard CD player sold and $66 for every portable CD player sold. The manager's target is to make at least $405 a day on
sales from standard and portable CD players. Write an inequality that represents the
numbers of both kinds of CD players that can be sold to reach or beat the sales target.
Let s represent the number of standard CD players sold and p represent the number of
portable CD players sold. Then graph the inequality.
