Answer: 360 mg of the medicine will be detected after 48 hours
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
P represents the initial dosage of the medicine.
A represents the final dosage of the medicine after t hours.
t represents the number of hours.
r represents the rate of decay
From the information given
P = 1000 mg
r = 40% = 40/100 = 0.4
The expression becomes
A = 1000(1 - 0.4)^t
A = 1000(0.6)^t
In 48 hours, t = 2
Therefore,
A = 1000(0.6)^2
A = 360
The amount of profit made if she walks 8 dogs is 63.25
<h3>Equations and expression</h3>
Given the equation for expressing the profit made as:
p(d) = 7.50d+3.25
where:
d is the number of dogs walked.
if she walks 8 dogs, the profit made will be expressed as:
p(8) = 7.5(8) + 3.25
p(8) = 60 + 3.25
p(8) = 63.25
Hence the amount of profit made if she walks 8 dogs is 63.25
