Question 118014: 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-yeaar-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 fiind the basal energy requirement if her weight is 53.2 kg.

You can put this solution on YOUR website! 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-yeaar-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 fiind the basal energy requirement if her weight is 53.2 kg.
------------------
You have two points that relate weight to B:
(45,1300) and (50,1365)
------------------------
slope = (1365-1300)/(50-45) = 65/5 = 13
Find the intercept:
1300=13*45 + b
b = 715
-------------
EQUATION:
B(x) = 13x + 715
-----------------
Find the equation and fiind the basal energy requirement if her weight is 53.2 kg.
B(53.2)=13*53.2+715
B(54.2) = 1406.60
