Answer:
The amount that the movie-streaming service charges Justin's bank account each month is $13. To find out how much Justin will be charged in one year, we need to multiply this monthly charge by the number of months in a year (12):
Total charges in one year = Monthly charge x Number of months in a year
Total charges in one year = $13 x 12
Total charges in one year = $156
Therefore, the movie-streaming service will charge Justin's bank account a total of $156 in one year.
