25.  We have this equation

y  =  497 (1/2)x/38    where  y is the amount remaining after x  days have elapsed

[ This is the first answer ]

After 4 days have elapsed, the amt remaining is

497(1/2)4/38  ≈  462.06  kg

26.    log 4 1024

We can use the change-of-base theorem, here

The answer is given by :

log 1024  /  log 4   =

5
