1. The problem states that for Project C, the allocated budget for design is 38% of £925,000. 2. Calculate the allocated budget for design: $$\text{Allocated design budget} = 0.38 \times 925000 = 351500$$ 3. You actually spend only 21% of the overall budget on design: $$\text{Actual design spending} = 0.21 \times 925000 = 194250$$ 4. The amount saved relative to the allocated budget for design is the difference between allocated and actual spending: $$\text{Savings} = 351500 - 194250 = 157250$$ 5. Therefore, you have saved £157250 relative to your allocated budget for design.
