This is a classic transportation problem where we need to minimize the shipping costs from supply points (Tampa, Miami, and Fresno) to demand points (New York, Philadelphia, Chicago, and Boston), considering the given constraints.

### Steps to solve this problem:

1. **Identify Supply and Demand:**
   - Tampa has a supply of 200 units.
   - Miami has a supply of 200 units.
   - Fresno has a supply of 200 units.
   - Total supply: \( 200 + 200 + 200 = 600 \).
   - Demand:
     - New York: 130 units.
     - Philadelphia: 170 units.
     - Chicago: 100 units.
     - Boston: 150 units.
   - Total demand: \( 130 + 170 + 100 + 150 = 550 \).

   Since the total supply (600) is greater than the total demand (550), an extra supply of 50 units exists.

2. **Shipping Costs:**
   The table shows the shipping cost in hundreds of dollars from each supply point to each demand point. There's also a constraint: no shipment is allowed from Miami to Chicago.

3. **Formulation as a Linear Programming Problem:**
   The objective is to minimize the total cost. Let:
   - \( x_{TN} \) be the amount shipped from Tampa to New York.
   - \( x_{TP} \) be the amount shipped from Tampa to Philadelphia.
   - \( x_{TC} \) be the amount shipped from Tampa to Chicago.
   - \( x_{TB} \) be the amount shipped from Tampa to Boston.
   - Similarly, define \( x_{MN}, x_{MP}, x_{MC}, x_{MB}, x_{RN}, x_{RP}, x_{RC}, x_{RB} \).

   **Objective Function:**
   Minimize:
   \[
   9x_{TN} + 14x_{TP} + 12x_{TC} + 17x_{TB} + 11x_{MN} + 10x_{MP} + 6x_{MC} + 10x_{MB} + 12x_{RN} + 8x_{RP} + 15x_{RC} + 7x_{RB}
   \]

4. **Constraints:**
   - Supply constraints:
     - \( x_{TN} + x_{TP} + x_{TC} + x_{TB} \leq 200 \) (Tampa supply).
     - \( x_{MN} + x_{MP} + x_{MC} + x_{MB} \leq 200 \) (Miami supply).
     - \( x_{RN} + x_{RP} + x_{RC} + x_{RB} \leq 200 \) (Fresno supply).
   - Demand constraints:
     - \( x_{TN} + x_{MN} + x_{RN} = 130 \) (New York demand).
     - \( x_{TP} + x_{MP} + x_{RP} = 170 \) (Philadelphia demand).
     - \( x_{TC} + x_{MC} + x_{RC} = 100 \) (Chicago demand).
     - \( x_{TB} + x_{MB} + x_{RB} = 150 \) (Boston demand).
   - Additional constraints:
     - \( x_{MC} = 0 \) (No shipment from Miami to Chicago).

5. **Solution Approach:**
   To find how much should be shipped from Tampa to New York, you would need to solve this transportation problem using either the **Northwest Corner Method** or more efficient optimization methods like **Linear Programming (Simplex Method)**.

Would you like a detailed step-by-step computation or details on the solving process?

### 5 Follow-up questions:
1. How do we determine the initial feasible solution for a transportation problem?
2. What are the advantages of using the Simplex Method for such optimization problems?
3. How do we handle situations where supply exceeds demand in transportation problems?
4. Can the transportation problem be solved graphically?
5. What methods can be used to check if the solution obtained is optimal?

**Tip:** You can use online tools or software like Excel's Solver or Python (using libraries like PuLP) to solve transportation problems more efficiently.
