Question

Your cell phone plan costs $29.99 plus $0.17 for each text message you send or receive. You have at most $34 to spend on your cell phone bill. Remember to define your variable and show work.

Answer 1

Let's define the following variables:

x = number of text messages sent or received

c = cost of text messages

Total cost = $29.99 + c

To find the maximum number of text messages you can send or receive, we need to set the total cost equal to $34 and solve for x:

$34 = $29.99 + c
c = $34 - $29.99
c = $4.01

Since each text message costs $0.17, you can send or receive a maximum of $4.01 / $0.17 = 23.53 text messages, which rounds down to 23 text messages.
