SOLUTION: Basal energy requirement. The basal energy requirement B is the number of calories that a person needs to maintain the life process. For a 28-year-old female with a height of 160 c

Question 322850: Basal energy requirement. The basal energy requirement B is the number of calories that 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. If her weight increases to 50 kg, then B is 1365 calories. There is a linear equation that expresses B in terms of her weight w.

Find the equation and find the basal energy requirement if her weight is 53.2 kg.

For a 28-year-old female with a height of 160 centimeters and a weight of 45 kilograms (kg), B is 1300 calories. If her weight increases to 50 kg, then B is 1365 calories.
There is a linear equation that expresses B in terms of her weight w.
Points relating weight and basal energy: (45,1300) and (50,1365)
---
slope = (1365-1300)/(50-45) = 65/5 = 13
-------
intercept:
B = m*w + b
1300 = 13*45 + b
b = 1300-13*45 = 715
---
Equation: Basal energy reqt = 13(weight) + 715
--------------------
Find the equation and find the basal energy reqt if her weight is 53.2 kg.
--------
Basal = 13*53.2 + 715 = 1406 calories
