Question

For Amy's cell phone plan, she pays $30 per month and $0.05 per text message. She wants to keep her bill under $60 per month. Which inequality represents the texts, t, Amy can send each month while staying within her budget?

Answer 1

.05x + 30 < 60

Explanation:

.05x + 30 < 60

.05 is the cost per text. Since we don't know how many text messages she sends, we have to use x to represent it. We know she pays $30 every month no matter what so, we can write .05x + 30. < means it has to be LESS than $60 NOT EQUAL TO, but less than.

I hope this helps you out!
