Answer:
A) 21.25 + 0.1m <= 60
B) 387
Step-by-step explanation:
I think the problem means to say that the first 1000 text messages are included in the $21.25 plan, and messages above the included 1000 cost $0.10 each.
A)
Let m = number of text messages above 1000.
0.1m is the cost of the messages past the included 1000.
The cost of the plan ($21.25) plus the cost of the messages above 1000, must cost up to $60.
21.25 + 0.1m <= 60
B)
21.25 + 0.1m <= 60
0.1m <= 38.75
m <= 38.75/0.1
m <= 387.5
Answer: 387
