Question

A person is trying to quit chewing gum. They decide they will have 64 pieces in week 1, but each week has half as many as the week before. How many weeks until they've reached their goal of 0 pieces a week?

Answer 1

8 weeks

Explanation:

week 1=64

week2=32

week3=16

week4=8

week5=4

week6=2

week7=1

week8=.5=0

Answer 2

Answer: Not exactly 0 pieces a week, but it'll take them at least 6 weeks to get rid of their habit.

Explanation:

64/2=32/2=16/2=8/2=4/2=2/2=1

Just continually divide that number by 2 until it reaches 1.
