Step-by-step explanation:
d = DVD player, with $75 profit
For every DVD player sold, the shop would earn 75d
c = cordless phone, with $30 profit
For every DVD player sold, the shop would earn 30c
The total profit of the score would be the profit from d and c summed up, which is: 30c + 75d
"The store wants to make a profit of at least $255.00 from its sales of DVD players and cordless phones."
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: 30c+%2B+75+d+%3E=+225
If wanted, it can be simplified with a simple division by 15
