The store makes a $75 profit on the sale of each DVD player(d) and a $30 profit on the sale of each cordless telephone(c) The store wants to make a profit of at least $255.00 from its sales of DVD players and cordless phones.

You can put this solution on YOUR website! d = DVD player, with $75 profit
For every DVD player sold, the shop would earn 75d
c = cordless phone, with $30 profit

This is merely a fancy way of saying that the total profit should be equal to or bigger than $255
The inequality would then be:
If wanted, it can be simplified with a simple division by 15:
