Question

Nadine can send or receive a text message for 15 cents or get an unlimited number for 5 dollars. Write and solve an inequality to find how many messages she can send and receive so the unlimited plan is cheaper than paying for each message.

Answer 1

$0.15x>$5.00
x>33.3333
So if she sends or receives more than 33 text messages, she will be paying more than $5.00.
