A pay phone at a shopping mall charges $0.68 for the first four minutes and $0.21 for each extra minute (or part of a minute). Find the cost of a 13.44-minute call on this phone

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
