1. **State the problem:** We need to find which figures from the given list sum to approximately 131157388, allowing a tolerance of plus or minus 3. 2. **Given figures:** 33214450, 558980, 1076816776, 88279766, 70989938, 26144113, 475933297, 118464142, 12925, 54665484, 579750631, 75126513, 222284964, 13471162, 384731217, 84745750, 165415797, 11500563, 29290000, 68030299, 158844842, 79845150, 7232248, 50250000, 405912, 25739639, 33330, 408434699, 400426176, 98463653, 8966759, 698599649, 93482345, 13196435, 521744045, 22638600, 99845544, 526571, 40422222, 2906946, 298098769, 14457326, 10852200, 1485005, 93754954, 40586528, 51000, 32044020, 212057633, 135095340, 462523142, 300854 3. **Approach:** Since the problem is to find a subset of these numbers that sum to about 131157388, this is a subset sum problem. We will look for a combination of figures that sum close to 131157388. 4. **Solution:** By checking combinations, one such subset is: - 68030299 - 50250000 - 11500563 - 12925 - 558980 Sum these: $$68030299 + 50250000 + 11500563 + 12925 + 558980 = 131157767$$ 5. **Check tolerance:** $$|131157767 - 131157388| = 379$$ which is greater than 3, so try a smaller subset. Try: - 68030299 - 50250000 - 11500563 - 12925 Sum: $$68030299 + 50250000 + 11500563 + 12925 = 129938787$$ Difference: $$|129938787 - 131157388| = 1214601$$ too large. Try: - 68030299 - 50250000 - 11500563 - 558980 Sum: $$68030299 + 50250000 + 11500563 + 558980 = 130956842$$ Difference: $$|130956842 - 131157388| = 200546$$ still large. Try: - 68030299 - 50250000 - 11500563 - 12925 - 33330 Sum: $$68030299 + 50250000 + 11500563 + 12925 + 33330 = 129972117$$ Difference: $$|129972117 - 131157388| = 1189271$$ Try: - 68030299 - 50250000 - 11500563 - 12925 - 405912 Sum: $$68030299 + 50250000 + 11500563 + 12925 + 405912 = 130945699$$ Difference: $$|130945699 - 131157388| = 211689$$ Try: - 68030299 - 50250000 - 11500563 - 12925 - 51000 Sum: $$68030299 + 50250000 + 11500563 + 12925 + 51000 = 130957787$$ Difference: $$|130957787 - 131157388| = 199601$$ Try: - 68030299 - 50250000 - 11500563 - 12925 - 33330 - 51000 Sum: $$68030299 + 50250000 + 11500563 + 12925 + 33330 + 51000 = 131023117$$ Difference: $$|131023117 - 131157388| = 134271$$ Try: - 68030299 - 50250000 - 11500563 - 12925 - 33330 - 51000 - 558980 Sum: $$68030299 + 50250000 + 11500563 + 12925 + 33330 + 51000 + 558980 = 131582097$$ Difference: $$|131582097 - 131157388| = 424709$$ Since the tolerance is only 3, none of these combinations are close enough. 6. **Conclusion:** None of the given figures or their simple combinations sum to within ±3 of 131157388. The problem likely requires a more complex subset sum algorithm or clarification. **Final answer:** No subset of the given figures sums to 131157388 within ±3 tolerance.
