Question

A candy distributor needs to mix a 10% fat-content chocolate with a 40% fat-content chocolate to create 100 kilograms of 22% fat- content chocolate. How many kilograms of each kmd of chocolate must they use?

Answer 1

Let n be the 40%, and 100-n be the 10%. Then:
.4n+.1(100-n)=.22(100)
.3n+10=22
.3n=12
n=40
The candy distributor needs 40kg of 40%, and 60kg of 10%
