Elmer, the circus Elephant, is currently three times older than Leo, the circus Lion. In five years from now, Leo the circus Lion will be exactly half as old as Elmer, the circus Elephant. How old is Elmer today?
A) 10
B) 15
C) 17
D) 22
E) 25
Decode this by going word-by-word to make an equation.
E=3L
(L+5) = .5(E+5)
(L+5) = .5(E+5)
L+5 = .5(3L+5)
L+5 = 1.5L + 2.5
2.5 = 0.5L
L=5 years old
E= (3)(5) = 15 years old
B
