Answer 1

Answer: A.

Step-by-step explanation:

.10 for the first minute.

.05 for the four minutes after.

.05 x 4= .20

.20 + .10= .30

This is the total cost for one phone call.

To get the total for two phone calls you would multiply the total by 2:

.30 x 2= .60

Therefore your answer would be A.
