$2^{10}=1024$

After $10$ years.

$2^7=128$

$2^{11}=2028$

$2^3=8$

$2^{62}\approx 4.6117\times {10}^{18}$

0.87
Formula: $C=150\cdot 0.{87}^t$

GR: Y1=150*0.87^X en Y2=75
using the graphic calculator you find $t\approx 4.98$ hours.

$0.{87}^{\left(24\right)}\approx 0.035$, so a decay percentage of approximately 96.5%.
