Final answer:
To find the best value for buying soft drink, the price per litre was calculated for each option and the most cost-effective choice was determined to be option c: 2 x 2lt bottles at $6.50 each, with a cost of $3.25 per litre.
Step-by-step explanation:
The correct option : d
- a. 1 x 3lt bottle at $14.50 each: Price per liter = $14.50 / 3 litres = $4.83 per litre
- b. 6 x 500ml at $3.00 each: A 500ml bottle is equal to 0.5 litres, so 6 x 0.5 litres = 3 litres. Price per liter = $3.00 x 6 / 3 litres = $6.00 per litre
- c. 2 x 2lt bottles at $6.50 each: Price per liter = $6.50 x 2 / 4 litres = $3.25 per litre
- d. 3 x 1.25lt bottles at $4.50 each: A 1.25lt bottle is equal to 1.25 litres, so 3 x 1.25 litres = 3.75 litres. Price per liter = $4.50 x 3 / 3.75 litres = $3.60 per litre
After comparing the price per liter for each option, option c is the most cost-effective choice at $3.25 per litre.
