Question 880401: In a group of a dozen horses, some are 9 yrs old and the reminder are 11 yrs old. The total of their ages is 122. Find the age distribution Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! 11x + 9(12-x) = 122
2x = 14
x = 7, number of 11 year olds. 5 nine year olds.
and...
77 + 45 = 122
