Answer:
[tex] 25P + 55R \ge 225 [/tex]
Step-by-step explanation:
P = number of portable DVD players; profit: $25 each
R = number of DVD recorders; profit $55 each
Profit for all portable DVD players sold: 25P
Profit for all DVD recorders sold: 55R
Total profit: 25P + 55R
Since you want the profit to be at least $225, at east $225 means $225 or more, so we use teh greater than or equal to symbols.
[tex] 25P + 55R \ge 225 [/tex]
