Question 1201962: A 2 bowl set has the following description:
The lid is interchangeable.
Weight of larger bowl: 12 oz. without lid.
With lid, larger weighs twice as much as smaller without lid.
With lid, smaller weighs one third more than larger without lid.
Calculate weight of lid.
Let A = larger.
Let B = smaller.
Let C = lid.
A = 12.
A + C = 2(B).
A = 1/3(B + C)
Not sure if set up correctly and how to solve.
