marin [14]

Answer:

option.D

Step-by-step explanation:

each day it changes by $-73\frac{1}{4}$

so for two days , the elevation becomes $-73\frac{1}{4}$ + $-73\frac{1}{4}$

for 3 days : $-73\frac{1}{4}$ + $-73\frac{1}{4}$ + $-73\frac{1}{4}$

so, for n days, $-73\frac{1}{4}$ + ........ n times

= n* $-73\frac{1}{4}$

therefore, for x days, elevation = x* $-73\frac{1}{4}$

as it is given that after certain days this elevation has reached $-366\frac{1}{4}$

so, x* $-73\frac{1}{4}$ = $-366\frac{1}{4}$

It doubles every 4 hours, so after 24 hours there will be 6 doublings.
2^6 = 64
So, the population will be (3,000,000 * 64) or 192,000,000 in 24 hours.
