Step-by-step explanation:
First you would need to dive what you have of each ingredient by how much you need for 6 people.
Flour: 450 ÷ 150 = 3
Sugar: 380 ÷150 = 2
Cocoa: 300 ÷ 120 = 2.5
Eggs: 8 ÷ 3 = 2.7
then you look at the total batches each could make and average it to 2 batches. then multiply 6 by 2.
6×2= 12
so all together, the maximum amount of people you can make for is 12.
