A secure Year 10 response, annotated to show which success criterion each part meets. It is also your answer key. Best value: posters £32.00 (pack of 50), leaflets £30.00 (Print Cwm), venue £70.00 (Canolfan Gymunedol). Full budget: £483.30. The limit is £500 − £50 = £450.00, so the budget is £33.30 over. Any cut that saves at least £33.30 is correct; three good options are shown below.
| Item | Option 1 | Option 2 | Best value |
|---|---|---|---|
| 40 posters | Print Cwm: 40 × £0.85 = £34.00 | Siop Argraffu: 1 pack of 50 = £32.00 | Siop Argraffu, £32.00. Cheaper by £2.00, with 10 spare. |
| 500 leaflets | Print Cwm: 500 × £0.06 = £30.00 | Siop Argraffu: 2 packs × £22.00 = £44.00 | Print Cwm, £30.00 |
| Venue | Neuadd y Dref: 4 × £18.00 = £72.00 | Canolfan: £55.00 + £15.00 = £70.00 | Canolfan, £70.00 |
The pupil buys whole packs, adds the cleaning fee, and notices that the pack price wins even though it gives more posters than needed. Evidences criterion 1.
| Item | Working | Cost |
|---|---|---|
| Refreshments | 70 × £1.50 | £105.00 |
| Banner | VAT: 10% of £48 = £4.80, so 20% = £9.60. £48.00 + £9.60 | £57.60 |
| Speaker travel | 23 × 2 = 46 miles. 46 × £0.45 | £20.70 |
| Badges | 100 × £0.38 | £38.00 |
| Adverts | 14 × £5.00 | £70.00 |
| Photo booth | Fixed price | £60.00 |
The pupil remembers the return journey for the speaker and shows the VAT step by step. Evidences criterion 2.
| Item | Cost (£) |
|---|---|
| Posters | 32.00 |
| Leaflets | 30.00 |
| Venue | 70.00 |
| Refreshments | 105.00 |
| Banner (including VAT) | 57.60 |
| Speaker travel | 20.70 |
| Badges | 38.00 |
| Adverts | 70.00 |
| Photo booth | 60.00 |
| Total | 483.30 |
Every value has 2 decimal places and the total is correct. Evidences criterion 3.
(a) 10% of £500 = £50.00 contingency. Most the forum can spend: £500.00 − £50.00 = £450.00.
(b) No. £483.30 − £450.00 = £33.30 over.
(c) I would run the adverts for 7 days instead of 14. That costs 7 × £5.00 = £35.00, saving £35.00. New total: £483.30 − £35.00 = £448.30, which is £1.70 under the limit.
Other correct cuts: remove the badges (saves £38.00, total £445.30), or remove the photo booth (saves £60.00, total £423.30).
The pupil finds the limit, works out the gap and chooses a cut that closes it with money to spare, and checks the new total. Evidences criterion 4.
Publicity with 7 days of adverts: £32.00 + £30.00 + £57.60 + £38.00 + £35.00 = £192.60. £192.60 ÷ £500 × 100 = 38.5% of the grant.
If the badges were cut instead: £189.60, which is 37.9%. If the photo booth were cut instead: £227.60, which is 45.5%.
The percentage is of the whole grant, as the question asks. Evidences criterion 3.
We compared two suppliers for printing and two venues, and chose the lowest total cost each time, which saved £18.00 compared with the dearer options. We cut the social media adverts from 14 days to 7, because most people decide to come in the last week and our posters, leaflets and speaker still reach young carers directly. We have kept £51.70 unspent, which is more than the £50.00 contingency the grant requires.
Three clear sentences for the council, each with a figure. Savings: £2.00 on posters, £14.00 on leaflets and £2.00 on the venue make £18.00. Unspent: £500.00 − £448.30 = £51.70. Evidences criterion 5.
