derrick gave half of his candy to cindy. cindy gave 1/3 of the pieces to kasey. kasey gave 1/5 of candy she gave to bill. Bill got 5 pieces of candy. How many did they start with
Answer provided by our tutors
let 'x' represent the number of candies that they started with
Derrick has: x
Cindy got: (1/2)x
Kasey got: (1/3)(1/2)x
Bill received: (1/5)(1/3)(1/2)x and we know that he received 5 candies thus we have:
(1/5)(1/3)(1/2)x = 5
by solving we find:
x = 150 pieces of candy
