DAY 105
A recycling plant gives 1 free bottle of soda pop for every 5 recycled bottles. How many free sodas would you get if you recycled 77 bottles?

Answer:

19.......77/5 = 15 free bottles + 2 left over......15/5 = 3 free bottles + the 2 left over..... these 3 + the 2 left over make 5.......these 5 yield 1 free bottle: 15 + 3 + 1 = 19
