Answer:
d.) 81
Step-by-step explanation:
f(2) would be 27 and 27x3 is 81.
81/3=27
27/3=9

Option C is correct...hope this helps:)
Answer:
D.) 7
Step-by-step explanation:
To calculate the check digit, multiply every even-position digit (when counted from the right) in the number by two. If the result is a two digit number, then add these digits together to make a single digit (this is called the digital root):
Odd numbers: (1.)= 8 (3.)= 4 (5.)= 6 (7.)= 0 (9.)= 4 (11.)= 6 (13.)= 2 (15.)=(1 + 6)= 7
Even numbers: (2.)= 3 (4.)= 8 (6.)= 1 (8.)= 3 (10.)= 6 (12.)=5 (14.)=0
To this total, we then add every odd-position digit:
Odd = 37
Even = 26
This will result in a total:
37 + 26 = 63
The check-digit is what number needs to be added to this total to make the next multiple of 10:
Next multiple of 10 is 70.
70 - 63 = 7
Answer:
7
