at 0 1 9 per bush. 1 10 at 0 9 10 per bush. 5 18 0

2. When the multiplier, that is, the quantity, is a composite number, and greater than 12, take any two such numbers as when multiplied together, will exactly produce the given quantity, and multiply first by one of those figures, and that product by the other; and the last product will be the answer.

EXAMPLES.

What cost 28 yards of cloth, at 6s. 10d. per yard? £. s. d.
