Ali has a 64 gram bar of chocolate. on day 1 he eats half of his chocolate. on day 2 he eats half of what is left. he does the same each day.
a. when will he have only 1 gram left?
b. how much would a bar of chocolate need to weigh to last all 14 days?

A: Day 6

B: 8196 grams (He will become obese for sure)

Step-by-step explanation:

Part A:

As you can infer from the problem, Ali halves his bar everyday, regardless of how the bar is.

Day 1= 32 grams left

Day 2= 16 grams left

Day 3= 8 grams left

Dat 4= 4 grams left

Day 5= 2 grams left

Day 6=1 gram left

He will have one gram left on Day 6

Part B:

This part is basically vice versa. Instead on halving, we need to be doubling. I will do Part a in reverse until Day 14 comes

Day 1= 1

Day 2= 2

Day 3= 4

Day 4= 8

Day 5= 16

Day 6= 32

Day 7 = 64

Day 8= 128

Day 9= 256

Day 10= 512

Day 11= 1024

Day 12= 2048

Day 13= 4096

Day 14= 8192

He will need 8192 grams of chocolate!!!

okay wait before i answer, is this for your points on a graph?
