Expressed as a percentage

Proportion of Salt =12.5%
<u>Cup C</u>
Proportion of Salt = 12.75%

Answer:
Option A.Exponential decay, 55% decrease
we have
This is a exponential function of the form
where a is the initial value
b is the base
b=(1+r)
r is the rate of change
In this problem
a=54
b=0.45
so
0.45=1+r
r=0.45-1
r=-0.55
Convert to percentage
r=-55% ------> is negative because is a exponential decay
