Out of 250 racers who started the marathon, 224 completed the race, 19 gave up, and 7 were disqualified. What percentage did not complete the marathon? Round your answer to the nearest tenth of a percent.

To find the percentage of racers who did not complete the marathon, we need to consider both those who gave up and those who were disqualified. 1. **Total racers**: 250 2. **Racers who completed the race**: 224 3. **Racers who gave up**: 19 4. **Racers who were disqualified**: 7 Now, we can calculate the total number of racers who did not complete the marathon: \[ \text{Racers who did not complete} = \text{Racers who gave up} + \text{Racers who were disqualified} \] Substituting the known values: \[ \text{Racers who did not complete} = 19 + 7 = 26 \] Next, we calculate the percentage of racers who did not complete the marathon: \[ \text{Percentage not completed} = \left( \frac{\text{Racers who did not complete}}{\text{Total racers}} \right) \times 100 \] Substituting the values: \[ \text{Percentage not completed} = \left( \frac{26}{250} \right) \times 100 \] Now, let's calculate this value. \[ \text{Percentage not completed} = 0.104 \times 100 = 10.4 \] Finally, rounding to the nearest tenth of a percent, we find that: \[ \text{Percentage not completed} = 10.4\% \] Thus, the percentage of racers who did not complete the marathon is **10.4%**.
