Calculate the protein intake of Miss Exercise, who weighs 112 lb.

Use the formula:
[tex]\[ (0.45)(w - \text{lb}) = (w - \text{kg}) \][/tex]

The recommended protein intake in grams is numerically equal to the person's weight in kilograms.

How much protein in grams should she consume?

A. 112.45
B. 111.55
C. 248.89
D. 50.4

Answer :

To calculate Miss Exercise's protein intake, we need to follow these steps:

1. Convert the Weight from Pounds to Kilograms:
- We start by converting Miss Exercise's weight from pounds to kilograms. We are given that 1 pound is approximately equal to 0.45 kilograms.
- Miss Exercise weighs 112 pounds. To convert her weight into kilograms, we multiply her weight in pounds by 0.45.

[tex]\[
\text{Weight in kilograms} = 112 \times 0.45 = 50.4 \, \text{kg}
\][/tex]

2. Calculate the Recommended Protein Intake:
- The recommended protein intake in grams is numerically equal to a person's weight in kilograms.
- Since Miss Exercise's weight is 50.4 kilograms, her recommended protein intake would also be 50.4 grams.

Therefore, Miss Exercise should consume 50.4 grams of protein to meet her recommended intake based on her weight.
