No, the steak is not within the 800 calories limit.

Explanation:

You need to determine whether a 20 ounces "Farmhand Cut" of prime rib at Farmer Browns Steak House is whithn the 800 calories from fat limit that a person on a 2400 calorie per day diet can consume.

See:

6.0 ounces is fat (good fat)

Fat contains 9.0 calories per gram: 9.0 cal/g

Convert 6.0 ounces to grams

1 ounce = 28.35 g

1 = 28.35 g/ounce

6.0 ounce * 28.35 g/ounce = 107.1 g

Calculate the calories from fat:

107.1 g * 9.0 cal/g = 1,530.9 cal

1,530.9 cal is way more than the 800 cal limit, hence this steak is not within the limit.
