Question

An electronics store makes a profit of $69 for every standard DVD player sold and $85 for every portable DVD player sold. The manager's target is to make at least $415 a day on sales from standard and portable DVD players. Write an inequality that represents the numbers of both kinds of DVD players that can be sold to reach or beat the sales target. Let s represent the number of standard DVD players sold and p represent the number of portable DVD players sold. Then graph the inequality.

Explanation:

The store's profit is the sum of the profit on each player multiplied by the number of players. That is, the profit on standard players is 69s, and that on portable players is 85p. The manager wants the sum of these to be more than 415.
