Question

Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own?

84
98
112
168

Answer 1

Amanda has 112 stamps.!!!!!!

Answer 2

S=L/2, A=2L/3

S+L+A=364, using S and A from above we get:

L/2+L+2L/3=364

(3L+6L+4L)/6=364

13L/6=364

13L=2184

L=168, and since A=2L/3

A=2(168)/3=112

So Amanda has 112 stamps.
