If 7 belly dancers altogether lose 20 pounds in 8 hours dancing,
how many more belly dancers would be needed to lose a total of
20 pounds in only 4 hours dancing, providing the new dancers
shed weight only half as fast as the original 7?
Solution to the Problem:
The answer is 14 more belly dancers.
Since the original 7 dancers can lose 20 pounds in 8 hours,
those same 7 dancers can lose 10 pounds in 4 hours.
That means that the additional dancers must lose 10 pounds in 4 hours.
Seven new dancers can lose 5 pounds in 4 hours
(since they lose weight only half as fast as the original 7).
Therefore, you need 14 new dancers to lose 10 pounds in 4 hours.
