Answer:
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
Step-by-step explanation:
Its a very simple Expression.
First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i.e t= 0.
For every four hour change , the temperature adds -3/2°c .
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
The expression to know the temperature is
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
Answer:
given,
Amount borrowed = $71500
Time = 200 days
interest rate = 7.5 %
ordinary interest rate for year = 
= $5362.5
exact interest rate for the year = 
= $2938.35
hence, the exact interest rate is less than the ordinary interest rate which means you should choose exact interest rate.
