Divide both sides by a
1/2=e^(-8.859t)
take the ln of both sides
ln0.5=-8.859t
divide both sides by -8.859
(ln0.5)/-8.859=t
0.078242147=t

Please note that a proportion is a true statement. Here, you need only pick the true statement from those offered. For example, here's the first choice written in more readable form:
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
