Each KC$-$area location has a maximum amount of traffic it can be $$sent$.$ In your solution, make sure that is not exceeded, but also make sure at least $60\%$ of that maximum amount of traffic $($fans$)$ is sent to each location.

Other requirements in your strategic plan for the fans:

a$)$ No more than $5000$ fans can be sent from any one hub to any one KC$-$area location. This considers all the combinations of hubs and the KC$-$locations.

b$)$ The weighted average of the fans $$spend factor$$ arriving at each of the three KC$-$area locations must be greater than or equal to $4\mathrm{.}95.$

c$)$ Consider each hub$$s most costly distribution path $-$ the total number of fans $($traffic$)$ sent combined along those $8$ paths cannot exceed $9500$ fans. What is $$most costly distribution path$$ for instance, for CHIC, it is Lawrence.

d$)$ Only integer decision variables.
