From the seating chart, we find the number of Business Class seats is 26 and Economy Class seats is 80. The simplified ratio can be calculated as follows:

$\text{Ratio} = \frac{26}{80} = \frac{13}{40}$.

The passenger should first get up and turn left, walking down the aisle towards the galley/kitchen. Upon reaching the first galley area, they should then turn right to proceed down the next aisle. Continuing forward, they will walk straight until they reach row 38. At row 38, the passenger's friend is seated on the right-hand side.

Based on the seating chart from ANNEXURE C, there are 26 Business Class seats. Assuming all seats are filled, there will be 26 Business Class passengers.

The number of aisle seats should be considered first. If we count the seats in Business Class and assume 2 of the 26 seats are aisle seats, the probability that a passenger in seat 2K does not have an aisle seat is:

$\text{Probability} = \frac{26 - 2}{26} \times 100 = 34.62\%$.

First, calculate the distance travelled in kilometers: 522,086 km. The flight time was from 17:14 to 04:11, which is 10.95 hours. The average speed in km/h can be calculated using:

$\text{Average Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{522,086 \text{ km}}{10.95 \text{ h}} = 47,728.96 \text{ km/h}$.

To convert km/h to knots, use the conversion factor (1 knot = 1.852 km/h):

$\text{Average Speed in knots} = \frac{47,728.96}{1.852} \approx 25,755.23 ext{ knots}$.

From Table 3, use the production cost formula:

• For A (800 belts):

$\text{Total cost} = 27,000 + 75 \times 800 = 87,000$

• For B (400 belts):

$\text{Total cost} = 27,000 + 75 \times 400 = 57,000$

• For C (total income from belts):

$\text{Total income} = 250 \times 400 = 100,000$.

The total income from the belts is:

$\text{Income from belts} = 250 \times 800 = 200,000$

And from T-shirts:

$\text{Income from T-shirts} = 175 \times 1,000 = 175,000$

Total Income = 200,000 + 175,000 = 375,000.

Graph points for selling belts will be created for the axes provided. For T-shirts, the income and production cost must be plotted accordingly to form the required graph.
