2.78 dollars
step-by-step explanation:
hello there!
first we multiply 10 to $ 0.21 ( we got the number 10 from the extra 10 minutes after the first 4 minutes )
10 + $ 0.21
= 2.10 dollars
then we need to add $ 0.68 to $ 2.10 dollars
$ 0.68 + $ 2.10
= 2.78 dollars
2.78 dollars is how much it costs for a 13.44 minute call!
i hope this helps you and please tell if there was a mistake in this, have a wonderful day! <3
