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?

Sagot :

If the first AMC 8 was in 1985, then the seventh AMC 8 was in 1991.

1991 - 12 = 1979

Samantha was born in 1979.
