Please Show step by step solution on excel and also the algebraic solution.

Optimization practice: Consider a company with five fixed warehouses and 10 customers, where the cost of serving each customer is provided in the following table: Make a model that minimizes the cost of serving each customer, given that each customer can only be served by one warehouse, and each warehouse can serve at most three customers (but must serve at least one customer). Provide the algebraic form of the model as well as the solution
