  13. A state park charges admission of $6 per person plus $3 for parking. Jo paid $27 when her car entered the park. Write and solve an equation to find the number of people in Jo's car. Be sure to explain what your variable represents.
    1. Let x = number of cars; 3x + 6 = 27; 7 cars
    2. Let x = number of people; 6x + 3 = 27; 4 people
    3. Let x = number of people; 3x + 6 = 27; 7 people
    4. Let x = number of cars; 6x + 3 = 27; 4 cars
