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?

Answer 1

9514 1404 393

Answer:

400

Explanation:

If the plan is used to its limit, the number of texts, t, that can be sent is ...

5 +0.05t = 25

0.05t = 20 . . . . . . . . . . subtract 5

t = 20/0.05 = 400 . . . divide by 0.05

A user can send 400 texts without exceeding plan limits.
