Final answer:
Paul needs to spend £350 and Margaret needs to spend £450.
This correct answer is A)
Step-by-step explanation:
To find out how much Paul and Margaret need to spend, we first need to find the total ratio of their contributions. The total ratio is the sum of the two parts in the ratio, which in this case is 7 + 9 = 16.
To find out how much Paul needs to spend, we can multiply his ratio part (7/16) with the total amount needed (£800). So, Paul needs to spend 7/16 * £800 = £350.
To find out how much Margaret needs to spend, we can multiply her ratio part (9/16) with the total amount needed (£800). So, Margaret needs to spend 9/16 * £800 = £450.
Therefore, Paul needs to spend £350 and Margaret needs to spend £450.
This correct answer is A)
