The fare from Sandton to Rhodesfield is R25.00.
Since the same fare applies in the other direction, the fare from Rhodesfield to Sandton is also R25.00.

• Cost for one return trip (daily): $\text{R}25.00 + \text{R}25.00 = \text{R}50.00$
• Weekly cost (5 days): $\text{R}50.00 \times 5 = \text{R}250.00$

The weekly cost is $\boxed{\text{R}250.00}$.

The tourist traveled from O.R Tambo International Airport to Marlboro.
From the table, "Airport to: Sandton, Marlboro, Rhodesfield" costs R105.00.

He paid $\boxed{\text{R}105.00}$ for this service.

The tourist needed to travel from Marlboro to Sandton.
From the table, "Other routes: Sandton - Marlboro" costs R19.00.
Since the same fare applies in the other direction, Marlboro to Sandton also costs R19.00.

He was expected to pay $\boxed{\text{R}19.00}$ for this service.

• Initial card balance: R300.00
• Cost of first trip (Airport to Marlboro): R105.00 (from 1.2.1)
• Cost of second trip (Marlboro to Sandton): R19.00 (from 1.2.2)

Total spent = $\text{R}105.00 + \text{R}19.00 = \text{R}124.00$
Money left on card = Initial balance - Total spent
Money left on card = $\text{R}300.00 - \text{R}124.00 = \text{R}176.00$

There was $\boxed{\text{R}176.00}$ left on his card.
