You can  put this solution on YOUR website! The function given below models the number of calories per day, f(x), a person needs to maintain life in terms of that person's weight, x, in kilograms (1 kilogram is approximately 2.2 pounds). Use this model and a calculator to determine how many calories per day the person, who weighs 65 kilograms (approximately 143 pounds), needs to maintain life.  
f(x)= 70x ^3/4 
f(65) = 70*65^3/4 
----- 
f(65) = 70*22.8921 
---- 
f(65) = 1602.44 
------ 
  
A person that weighs 65 kilograms needs about 1602 calories per day.  
(Round to the nearest calorie as needed.)
