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
The answer will be $13,439.16
The discounted price is $13.5. You do $18 and times it by 0.25. You will get 4.5. You then subtract the 4.5 from the $18 and you get $13.5
13 - 5 = 8
29 - 13 = 16
61 - 29 = 32
8 x 2 = 16
16 x 2 = 32
Next number would be : 32 x 2 = 64, 61 + 64 = 125
