Question

Been having trouble with this problem. I've always been bad with story problems so sorry if it's a bad question.

Mike's cell phone plan is $50 per month plus $0.10 per text message for each message. If Mike's cell phone bill is $112, for how many extra text messages was he billed?

Answer 1

Let's call the text messages "m", ok? So the equation for this is C(cost) = 50(cuz that doesn't ever change) + .10m (which means 10 cents per text message. If the cost is 112, here's your equation:
112=50+.1m
Solve for m. Can you do that?

Answer 2

"m" will be the number of text messages he was billed for.

Answer 3

It's not a bad question. And it's not too difficult, either. You can do this!

Answer 4

So I'm guessing you subtract 50 from both sides and you end up with 62=.1m?

Answer 5

Yep...go on...

Answer 6

Now what do you do?

Answer 7

What do you do with the .1?

Answer 8

Divide the 62 by .10 and get 620

Answer 9

So 620 messages?

You're right! He texted 620 messages! Sounds like my teenage girls!
