On Jerry's text messaging phone plan,

Question

On Jerry's text messaging phone plan, she paid $1.50 for every 30 messages she sent.

What is the her cost per message?

Answer 1

cost per message = $1.50 / 30.

Answer 2

Hi Ang,

Let's work through this together. The prompt tells us that for 30 messages sent the total was $1.50. So we can take $1.50 and divide that by 30 (number of messages sent) and this should give us the cost PER message.

1.50/ 30 = 0.05

This means that each message sent cost 0.05. To check this you can take the cost per message (0.05) and multiple by 30 ( total messages sent) and it should give you the total cost ( $1.50).!

check: 0.05 * 30 = $1.50

Hope this helps,

Carla
