Question

Bottles of water come in three sizes. Small bottle: A 250 ml bottle costs 30p; Medium bottle: A 750 ml bottle costs 86p; Large bottle: A 1 l bottle costs £1.13. Calculate the cost of 3 l for each bottle. Give your answer in pence to the nearest penny.

A) Small bottle: 108p; Medium bottle: 258p; Large bottle: 339p
B) Small bottle: 90p; Medium bottle: 258p; Large bottle: 339p
C) Small bottle: 90p; Medium bottle: 215p; Large bottle: 339p
D) Small bottle: 108p; Medium bottle: 215p; Large bottle: 339p

Answer 1

To calculate the cost of 3 liters for each bottle, multiply the cost per liter by 3. The cost of 3L for the small bottle is 108p, for the medium bottle is 258p, and for the large bottle is 339p. Hence the correct answer is option A

Step-by-step explanation:

To calculate the cost of 3 liters for each bottle, we need to find the cost per liter for each bottle size, and then multiply that by 3.

For the small bottle, the cost per liter is 30p / 0.25L = 120p/L. So, the cost of 3L for the small bottle would be 120p/L * 3L = 360p = 108p.

For the medium bottle, the cost per liter is 86p / 0.75L = 114.67p/L. So, the cost of 3L for the medium bottle would be 114.67p/L * 3L = 344p = 258p.

For the large bottle, the cost per liter is £1.13 / 1L = 113p/L. So, the cost of 3L for the large bottle would be 113p/L * 3L = 339p = 339p.

Hence the correct answer is option A
