Answer:
Original price = $ 280.66
New price = $319.11
Step-by-step explanation:
Let the original price be = x
Given 13.7% of original price resulted in 38.45 increase
That is,
13.7% of x = 38.45

Answer:
a) The highest temperature was registered on the sixth day after the onset of the illness.
b) The highest temperature of the patient is 101.8.
Step-by-step explanation:
Let
, we can find the maximum and minimum temperature of the patient by means of the First and Second Derivative Tests, whose procedure is described below:
First Derivative Test


Second Derivative Test

Which means that critical value found in the previous step is an absolute maximum and there is no absolute minimum.
a) The highest temperature was registered on the sixth day after the onset of the illness.
b) We evaluated the function at critical value found by First Derivative Test:


The highest temperature of the patient is 101.8.
