Answer 1

To represent the number of portable DVD players, let p represent the variable.
To represent the number of DVD recorders, let r represent the variable.

Given that the store makes a profit of $25 for every portable DVD player sold and $55 for every DVD recorder sold, we can express the profit made from selling p portable DVD players as 25p and the profit made from selling r DVD recorders as 55r.

The manager's target is to make at least $225 a day. So, the inequality representing the number of both kinds of DVD players that can be sold to reach or beat the sales target is:

25p + 55r ≥ 225.
