7 ballerinas dance for 8 hours and lose a total of 20 pounds. How many more ballerinas dancing would it take to lose a total of 20 pounds in only 4 hours, if the new dancers lost weight only half as fast as the original 7?
7 * 8 -> 20
to make it in 4 hours ; 14 x 4 -> 20
extra dancers = 7
but if the new dancers lost weight only half as fast as the original 7
then it would be 14. (d)
