Sam is collecting pennies. On the first day of the month, Samnis given 16 pennies. Each day after that he gets 4 more pennies. Which of the following equations defines how many pennies he has after the nth day?
A. an = 16n + 4 B. an = 4n + 16 C. an = 4n + 16 D. an = 64n - 64
N is the number of days that pass by. Each day Sam gets 4 more, meaning you would multiply the number of days by 4, before adding that number to the original number of pennies, which was 16.
