Answer 2

Answer:

$25.89$% is the percent of kilocalories in this meal that come from fat

Explanation:

Amount of calories in one gram of carbohydrate $= 4$

Amount of calories in one gram of protein $= 4$

Amount of calories in one gram of fat $= 9$

Now total calories in $121$ grams of carbohydrate

$= 121*4\\= 484$

Now total calories in $40$ grams of protein

$= 40*4\\= 160$

Now total calories in $25$ grams of fat

$= 25*9\\= 225$

Total calories $= 225 + 160+ 484\\= 869$

one kilocalories is equal to $1000$ gram calories

Total kilocalories is $= 0.869$

Total kilocalories in fat $= 0.0.225$

Thus, percent of kilocalories in this meal come from fat

$\frac{0.225}{0.869}* 100\\= 25.89$%
