Second question
The townof hatwood was founded in 1867 by hamilton haywood.uncle hay as he was known to all became a very rich man. Some say that this was because he was also a very frugal individual. As an example,uncle hay found that instead of throwing away the studs of used candles you could melt them down and turn them into new candles.it turned out that one new candle could be made of four candle studs.since uncle hay bought all of his candles in handy packs of 16 how many new candles was he able to make from each pack?

Candle stubs, not studs.

So what have you come up with? (Hint -- Draw a picture for each problem.)

A teacher assigned homework to his class and told the students that on each day after the first they must do twice he number of problems that they had done so far. If, at the end of five days, the students had completed one-third of the problems, how long will it take them to do all their problems?


end of 5 days = 1/3 of the problems done.
end of 6 days = twice that many additional problems done. So, how many problems have been done.

16 candles yield 16 stubs. How many stubs per new candle? And, how many new candles from a stub?
