use the rda for protein (0.8 gm/kg body weight) to calculate protein needs in a 40 year old who weighs 180 pounds and eats 2200 calories per day.
144 grams protein
110 grams protein
65 grams protein

Explanation:

Step1: Convert pounds to kilograms

1 pound = 0.453592 kg, so 180 pounds $\times0.453592$ kg/pound = 81.6466 kg

Step2: Calculate protein needs

RDA is 0.8 gm/kg. So protein needs = 81.6466 kg $\times0.8$ gm/kg = 65.3173 gm $\approx$ 65 grams

Answer:

65 grams protein
