Question

A phone plan has a limit of $25 that can be spent on text messages. The base cost of the text plan will cost a user $5. Each text will cost $0.05. How many text messages (t) can a user send without exceeding the plan limits? t ≤ 400 t < 400 t ≤ 600 t < 600

Answer 1

The answer is A)

Explanation:

Answer 2

The answer to this question would be: t ≤ 400

In this question, the limit of the bill is $25 and $5 is already paid out for the base cost. The remaining $20 is for paying the text message cost.
The cost is $0.05/ message, then the maximum message that could send would be: $20/ ($0.05/message)= 400 message
The answer would be t ≤ 400 or t<401 since sending you are still able to send 400 message, but not 401.
