For 24 cookies, 360g of sugar is required. To find the amount needed for 6 cookies, we calculate:

ext{Sugar needed} = 360g imes rac{6}{24} = 90g

Ashley has 520g of cranberries. The recipe requires 170g of cranberries to make 24 cookies. To see if she has enough for 80 cookies, we first find the required amount:

ext{Cranberries needed} = 170g imes rac{80}{24} \\ = 566.67g

Since Ashley has only 520g, she does not have enough cranberries. Therefore, Ashley is incorrect.

Darcie makes 100 cookies, and each packet contains 6 cookies. The number of packets is:

ext{Number of packets} = rac{100}{6} ext{ (approx. 16.67, so 16 full packets)}

Since each packet sells for £1.35, the total revenue is:

$$ext{Total money} = 16 ext{ packets} imes £1.35 = £21.60$$
