1. **State the problem:** We have a table showing the number of cars by color that went through a car wash in one day. We need to determine which TWO statements are supported by the data.
2. **List the data:**
- White cars: 30
- Red cars: 6
- Black cars: 24
- Blue cars: 15
3. **Calculate the total number of cars:**
$$30 + 6 + 24 + 15 = 75$$
4. **Check each statement:**
- Statement 1: "There were 80 cars that went through the car wash"
- Total is 75, so this is **false**.
- Statement 2: "Less than 22% of the cars were either red or blue"
- Number of red or blue cars: $6 + 15 = 21$
- Percentage: $$\frac{21}{75} \times 100 = 28\%$$
- 28% is not less than 22%, so this is **false**.
- Statement 3: "Over 50% of the cars were white"
- Percentage of white cars: $$\frac{30}{75} \times 100 = 40\%$$
- 40% is not over 50%, so this is **false**.
- Statement 4: "White and black cars combined accounted for 72% of the cars"
- Number of white and black cars: $30 + 24 = 54$
- Percentage: $$\frac{54}{75} \times 100 = 72\%$$
- This is **true**.
- Statement 5: "There were four times as many black cars as red cars"
- Ratio: $$\frac{24}{6} = 4$$
- This is **true**.
5. **Final answer:** The two correct statements are:
- White and black cars combined accounted for 72% of the cars
- There were four times as many black cars as red cars
