Spend on providing residential placements to children - Find a freedom of information request

I am writing with a request under the Freedom of Information Act. Could I ask, for the financial years 2018-2019, 2022-2023 and 2023-2024:

1. How much did your local authority spend on providing residential placements to children taken into the council's care? Please provide a breakdown for each year, including a projected spend for the rest of 2023-2024 if it is available.

2. Of that figure, how much of the figure was spent on private-sector residential placements? Again, please provide a breakdown for each year and include a projected spend for the rest of 2023-2024 if it is available.

3. How many children were taken into the council's care for each financial year?

1 and 2.
