You don't have to write the bottom part in your answer, everything under 'explanation' is only meant for your understanding

Part (b) answer^^
Since the difference between the large and small bottle is 1.5 litres, as found in part (a),
Volume of a large bottle can be written as:
vol. of large bottle = vol. of small bottle + 1.5
I used 'y' to represent the vol. of a small bottle. Given that 7.5 litres was used to fill up 2 large bottles and 3 small bottles completely, the total volume of the 3 small bottles and 2 large bottles is 7.5 litres. Hence, 3y + 2y + 2(1.5) = 7.5. Proceed to find the volume of one small bottle, y. Thn, find the volume of lemonade remaining by subtracting 0.3 from the volume of a small bottle. Add 7.5 to that value to find the volume of lemonade made initially.
