Eric has

2

boxes of apples, with the first box containing red and yellow apples and the second box containing green apples. Eric observes that the red apples make up

\tfrac{1}{2}

of the apples in the first box. He then moves all of the red apples to the second box, and observes that the red apples now make up

\tfrac{1}{3}

of the apples in the second box. Suppose that Eric has

28

apples in total. How many red apples does Eric have?
