To determine which person will most likely gain weight the slowest based on calorie consumption and expenditure, we need to compare the calorie intake and calorie usage of each person.
Let's analyze each person's data:
A. Madeline takes in 2,500 calories a day and uses 2,200 calories during the day.
B. Fernando takes in 2,550 calories a day and uses 2,500 calories during the day.
C. Dahlia takes in 2,000 calories a day and uses 1,900 calories during the day.
D. Wallace takes in 2,500 calories a day and uses 2,000 calories during the day.
To find out the net calorie balance for each person, we subtract the calories used from the calories consumed:
A. Madeline: 2,500 calories - 2,200 calories = 300 calories surplus
B. Fernando: 2,550 calories - 2,500 calories = 50 calories surplus
C. Dahlia: 2,000 calories - 1,900 calories = 100 calories surplus
D. Wallace: 2,500 calories - 2,000 calories = 500 calories surplus
The surplus indicates the extra calories that are not being used, which could lead to weight gain. Therefore, the person who will most likely gain weight the slowest is the one with the lowest surplus.
Comparing the surpluses, we see that Fernando has the smallest surplus of 50 calories. This means that Fernando will most likely gain weight the slowest among the given options.
So, the answer is B. Fernando takes in 2,550 calories a day and uses 2,500 calories during the day.
