The length of a classroom is 34 feet. what is this measurement in yards and feet?
a 17 yards 0 feet
b 11 yards 1 foot
c 8 yards 2 feet
d 5 yards 4 feet

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
