Question

Scaling up a recipe this recipe makes three dozen cookies. you want to make enough cookies so that 360 people each get two cookies. how will you scale up the recipe? how much of each ingredient will you need?

Answer 1

3 dozen= 36, you need 720.
720/36= 20.
This means you'll need to scale up the recipe to a factor of 20. In other words, you'll need to multiple the amount of each ingredient required by 20 in order to have enough cookies for 360 people to each have two.
