<PRE><B>Question 145143</B>
The basal energy requirement B is the number of calories a person needs to maintain the life process. 
For a 28-year-old female with a height of 160 centimeters and a weight of 45 kilograms (kg), B is 1300 calories. 
Data: (45,1300)
---------------------
If her weight increases to 50kg, then b is 1365 calories.
Data: (50,1365)
---------------------- 
There is a linear equation that expresses B in terms of her weight w.
slope = (1365-1300)/(50-45) = 65/5 = 13
Find the intercept: 1300 = 13*45 + b ; b = 715
EQUATION: Basal = 13(weight) + 715
-------------------------------
 Find the equation and find the basal energy requirement if her weight is 53.2 kg. 
B(53.2) = 13*53.2 + 715
B(53.2) = 1606.6
