1. If a man can earn 8 dollars in 1 week, what will he earn in 4 weeks?
Illustration.—It is evident, since a man can earn 8 dollars in 1 week, that in 4 weeks he will earn 4 times as much, and the result may be obtained by addition; thus, 8+8+8+8=32 dollars; or, by a more convenient process, by multiplying by 4, the number of times 8 dollars is to be taken; thus, 4 times 8 dollars are 32 dollars. Hence in 4 weeks he will earn 32 dollars.
