Question

The first AMC 8 was given in 1985 and it has been given annually since that time. Samantha turned 12 years old the year that she took the seventh AMC 8. In what year was Samantha born?

Answer 1

The seventh year is 1985 + 7 = 1992

if she was 12 years old in 1992, then 12 years earlier is 1980 - the year of her birth

answer is 1980

Answer 2

12-7=5

1985-5=1980

Samantha was born in 1980.
