Answer:
1. 16
2. 6
Explanation:
1. There are 4 sources that can ship to 4 different destinations. Each of the 4 can ship to any of the 4 destinations which means that the number of shipping lanes is;
= 4 * 4
= 16
2. There are 3 sources which means the fixed requirement for sources is 3. There are 3 destinations which means the fixed requirement for destinations is 3.
The total fixed requirements are;
= 3 + 3
= 6
