A25.5-g piece of cheddar cheese contains 37% fat, 28% protein, and 4% carbohydrate. the respective fuel values for protein, fat, and carbohydrate are 17, 38, and 17 kj/g, respectively. the fuel value for this piece of cheese is kj.

Thank you for posting your question here at . Below is the solution:

m(fat) = %fat x 25,5 = 0,37 x 25,5 = 9,435 g of fat 

m(protein) = %protein x 25,5 = 0,28 x 25,5 = 7,14 g of protein 

m(carbohydrate) = %carbohydrate x 25,5 = 0,04 x 25,5 = 1,02 g of carbohydrate 

E = m(protein) x 17 + m(fat) x 38 + m(carbohydrate) x 17 
E = (7,14 x 17) + (9,435 x 38) + (1,02 x 17) 
E = 497 kJ

The answer to that is 6

B.the point lies directly on the regression
