A healthy amount of body for young men is 8 to 20 percent of body weight. Calculate the range of body fat, in pounds, for a young man who weighs 150 pounds and for a young man who weighs 185 pounds.
0.08 * 150 = 12 Lbs, min.
0.20 * 150 = 30 Lbs, max.
Repeat for the 185 Lb. man.
To calculate the range of body fat in pounds for a young man, we need to follow these steps:
Step 1: Calculate the weight range based on the percentage provided (8% to 20%) in decimal form.
For a young man who weighs 150 pounds:
- Multiply 150 by 0.08 (8% in decimal form) to find the low end of the range.
- Multiply 150 by 0.20 (20% in decimal form) to find the high end of the range.
For a young man who weighs 185 pounds:
- Multiply 185 by 0.08 (8% in decimal form) to find the low end of the range.
- Multiply 185 by 0.20 (20% in decimal form) to find the high end of the range.
Step 2: Calculate the body fat range by subtracting the low end from the high end.
Let's calculate both scenarios:
For a young man who weighs 150 pounds:
Low end of the range: 150 (weight) * 0.08 (8% in decimal form) = 12 pounds
High end of the range: 150 (weight) * 0.20 (20% in decimal form) = 30 pounds
Body fat range: High end - Low end = 30 pounds - 12 pounds = 18 pounds
Therefore, the body fat range for a young man who weighs 150 pounds is 12 to 30 pounds.
For a young man who weighs 185 pounds:
Low end of the range: 185 (weight) * 0.08 (8% in decimal form) = 14.8 pounds
High end of the range: 185 (weight) * 0.20 (20% in decimal form) = 37 pounds
Body fat range: High end - Low end = 37 pounds - 14.8 pounds = 22.2 pounds
Therefore, the body fat range for a young man who weighs 185 pounds is 14.8 to 37 pounds.
