Okay, how can I help you? What's the question? I may not know it, but I'll try my best to help you.
Answer:
My best guess would be B and C since those are the only numbers that aren't multiples of 5, and all the values of a(n) are.
I need some details... If i can get a little more details with that "check all that apply" and i could get you an answer.
From birth to 5yo = 91,200
from 5 to 18yo = 167,000
therefore from birth to 18yo will cost 91,200 + 167,000 which is 258,200
Since the question says per year and thats the total cost of 18 years ( from 0 years to 18), we divide it by 18.
258,200 ÷ 18 = 14,344
Answer a: 14,344
