Answer:5 people were in each car.
Step-by-step explanation:
Let x represent the number of people that travelled in each car.
The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.
Seven cars filled and 7 more people traveled in a truck. This means that
7x + 7 = 42
Subtracting 7 from the left hand side and the right hand side of the equation. It becomes
7x + 7 - 7 = 42 - 7
7x = 35
Dividing the left hand side and the right hand side of the equation by 7, it becomes
7x/7 = 35/7
x = 5
x = 5
Step-by-step explanation:
I wasn't sure if you needed just x or if you needed the other angles so I did both.
Total cost = 15*14 ( 0.89 + 2.99 ) + 2(15 + 14) 0.19 = $825.82
