Answer
To find A, we need to sum the restaurant menu price and the tip (gratuity). We have:
Total cost = Restaurant menu price (R110) + Gratuity (R11) = R121.
Thus, A = R121.

Answer
From the chart, the total for Mr Delivery is R126. Given the meal price is R126 and delivery fee is R10, the delivery fee B is calculated as:
B = R126 - R116 = R10.
Step 4
Write down the difference between the highest price and the lowest price of the meal, excluding delivery/gratuity.

Answer
The highest price is from Uber Eats (R136) and the lowest price is from the Restaurant menu (R110).
The difference is:
Difference = R136 - R110 = R26.
