Sending text messages from Katrina's cell phone costs $0.19 per text message. From last month, she has a credit on her bill for
$9.50. How much more money will she need to pay for text messages this month if she has sent 158 messages?

Respuesta :

Answer:

Katrina will have to pay $21.02 this month.

Step-by-step explanation:

The cost per text message = $0.19

Last month credit = $9.50

The number of text messages sent this month = 158

So, the total cost of 158 texts = 158 x cost per text

= 158 x $0.19  = $ 30.52

So, her total bill = The amount spent on texts - The credit amount

                            = $ 30.52 - $9.50 = $21.02

So, Katrina will have to pay $21.02 this month.
