Solution Steps

Step 1: Finding suitable store doorways

The Pretzel shop will be located within the rectangle with vertices (9, 6), (9, 9), (15, 9), and (15, 6). We need to select two existing store doorways that, when a midpoint is calculated, will fall within this rectangle. Visually inspecting the map, the "Party Store" doorway at (6,7) and the "Shoes Express" doorway at (20,11) appear to be good candidates.

Step 2: Calculating the midpoint

The midpoint formula is: ((x₁ + x₂)/2, (y₁ + y₂)/2).

Using the coordinates for the "Party Store" (6, 7) and "Shoes Express" (20, 11):

Midpoint = ((6 + 20)/2, (7 + 11)/2) = (26/2, 18/2) = (13, 9)

Step 3: Verifying the midpoint

The calculated midpoint (13, 9) falls within the defined rectangular area of the Pretzel shop (9≤x≤15 and 6≤y≤9) since 9 ≤ 13 ≤ 15 and 6 ≤ 9 ≤ 9.

Final Answer:

The Pretzel shop doorway can be located at (13, 9) by selecting the "Party Store" and the "Shoes Express" doorways and using their midpoint.
