The price of 10 pounds of apples is d dollars. If the apples weigh an average of 1 pound for every 6 apples, which of the following is the average price, in cents, of a dozen such apples? The answer should be one of the following but I don't know how to set the problem up to solve it.
20d
50d over 3
5d
5d over 3
d over 20

10 lbs of apples = 10 x 6 = 60 apples
so the average price per apple is
d/60 dollars = 100 x d /60 cents
so a dozen apples would be
12 x 100 x d / 60 cents
