Cost of 10 balls = 36
Cost of one ball = 36 / 10 => 3.6
Cost of 48 balls = 48 × 3.6
=> 172.80

Answer:
50 feet
Step-by-step explanation:
Given:
Vertical height of lift by escalator (h) = 25 ft
Angle of inclination of escalator (x) = 30°
Now, the person traveling along the escalator is equal to the length of the escalator from bottom to top.
Now, a triangle can be constructed using the above scenario.
Consider a right angled triangle ABC with:
AB → Vertical height of escalator = 25 ft
AC → Length of escalator = ?
Now, using trigonometric ratio for sine, we can find the length AC.
This gives,
Therefore, the distance of travel of a person from bottom to top of the escalator is 50 feet.
