Foundation June 2023 Paper 2 Q18

18 Asha buys 180 cans of cola.

The cans are sold in packs.
There are 12 cans in each pack.
Each pack costs £3

(a) Work out the total cost of the cola Asha buys. (3)

Ethan buys a box of 24 cans of lemonade for £7
There are 330 ml of lemonade in each can.

(b) Work out the cost of 100 ml of lemonade.
Give your answer correct to the nearest penny. (3)

Mark scheme (a)

Answer	Mark	Mark scheme
45	P1	for a valid start to the process, eg \(180 \div 12\ (= 15)\) or \(3(.00) \div 12\ (= 0.25)\)
	P1	for complete process, eg \(\text{``}15\text{''} \times 3(.00)\) or \(180 \times \text{``}0.25\text{''}\)
	A1	for 45(.00)

Calculations can be in £ or p or a combination for both process marks

Mark scheme (b)

Answer	Mark	Mark scheme
9	P1	for a valid start to the process, eg cost of each can, eg \(7(.00) \div 24\ (= 0.2916...)\) or \(700 \div 24\ (= 29.16...)\) or total volume of 24 cans, eg \(330 \times 24\ (= 7920)\) or proportion of ml, eg \(330 \div 100\ (= 3.3)\)
	P1	for complete process, eg \(\dfrac{100}{330} \times \text{``}0.2916...\text{''}\ (= 0.08838...)\) or \(\dfrac{100}{330} \times \text{``}29.16...\text{''}\ (= 8.838...)\) or \(\dfrac{100}{\text{``}7920\text{''}} \times 7(.00)\ (= 0.08838...)\) or \(7(.00) \div 24 \div \dfrac{330}{100}\ (= 0.08838...)\) or \(7(.00) \div \dfrac{\text{``}7920\text{''}}{100}\ (= 0.08838...)\)
	A1	for 9

Calculations can be in £ or p
