The correct Answer is:
To solve the problem, we need to determine how many families have exactly one car based on the information provided. ### Step-by-Step Solution: 1. **Understand the Groups**: - We have two groups of families: - Families with at least one car (which includes families with one car and families with two or more cars). - Families with at least two cars. 2. **Identify the Numbers**: - Total families with at least one car = 250 - Total families with at least two cars = 60 3. **Set Up the Equation**: - Let \( x \) be the number of families with exactly one car. - Families with at least one car can be expressed as: \[ x + \text{(families with two or more cars)} = 250 \] - Since we know that families with two or more cars = 60, we can substitute this into the equation: \[ x + 60 = 250 \] 4. **Solve for \( x \)**: - Rearranging the equation gives: \[ x = 250 - 60 \] - Thus, \[ x = 190 \] 5. **Conclusion**: - Therefore, the number of families that have exactly one car is 190. ### Answer: 190 families have exactly one car. ---
