Final answer:
Cody, who currently weighs 50 pounds, is likely to gain an average of 7 pounds per year over the next two years. Thus, in two years' time, he is expected to weigh around 64 pounds. Since 62 pounds is the closest option to this estimate, option 3) 62 pounds is the most likely answer.
Step-by-step explanation:
The question revolves around predicting the weight gain of an 8-year-old boy, Cody, in a span of two years. Considering that children in middle childhood (which includes 8-year-olds) usually gain about 3.2 kg (7 lbs) per year, and since Cody weighs 50lbs currently, we can estimate his weight in two years:
Cody's current weight: 50 lbs
Expected weight gain over 2 years: 7 lbs/year × 2 years = 14 lbs
Expected weight in 2 years: 50 lbs + 14 lbs = 64 lbs
However, since there are no options exactly matching 64 lbs, we consider the normal weight variance in children's growth. Option 3) 62 lbs is the closest to our estimate and allows for the slight variation that can occur in an individual child's growth rate.
