Question 111232: We think we have the answer, but the answer does not appear on the worksheet as a possible solution.
A set of children's blocks contains 3 shapes, longs, flats & cubes. There are 3 times as many longs as cubes and 30 fewer flats than longs. If there are 600 blocks in all, how many longs are there?
600 = c + l + f
c = 3l
f = l -30
600 = 3l + l + l-30
600 = 5l - 30
630 = 5l
l = 126
Is this correct, or has something been transposed?
