trapecia [35]

Answer:

David will have the most cookies and he will have two cookies more than Jake

Step-by-step explanation:

1. Let's calculate how many cookies will David cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/8)

Number of cookies = 16

2. Let's calculate how many cookies will Jake cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/7)

Number of cookies = 14

David will have the most cookies and he will have two cookies more than Jake
