W = Woe-0.009
I
What percentage of its initial weight remains after 34 days?
A) 73.6%
B) 76.6%
C) 69.2%
D) 26.4%

Answer 1

A) 73.6%

Explanation:

The computation of the percentage is shown below

Given that

W = Woe^{-0.09t}

After 34 days

W = W_oe^{-0.009×34}

= 0.736W_o

Now the percentage is

= 0.736 × 100

= 73.6%
