Who is taking in more calories if the small bag of snickers are the exact same size: A person in a group where 5 people are shar

MrRa [10]

Answer:

A person in a group where 5 people are sharing 3 small bags of snickers

Step-by-step explanation:

Let the number of calories in one bag of snickers =x

Number of calories in 3 small bags of snickers =3x

If 5 people share 3 small bags of snickers, 1 person's share $=\dfrac{3x}{5}$

Number of calories in 2 small bags of snickers =2x

If 7 people share 2 small bags of snickers, 1 person's share $=\dfrac{2x}{7}$

We then compare the two.

Let x=1

$\dfrac{3}{5}=0.6$ calories per person\\\dfrac{2}{7}=0.29$ calories per person$

Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.
