Answer:
20.46 pounds
Step-by-step explanation:
- Since 16.5% of their body is fat you need to multiply the weight by that percentage
- you can do this by multiplying 124 by .165 which equals 20.46 pounds
It would be $1.76 for 1 lb, then you would times that by 61 and if it equals 10.62, it is proportional. I multiplied it and got $109.28/ 62 lbs so it can not form a proportion.
A- (6,-3) B- (9,-3) C- (9,-7)
