<em>See comment for complete question</em>
Solving (a): The initial charge
A linear function is represented as:
Where c is the initial value
By comparison:
Hence: The initial value is 40
Solving (b): Amount charged for 94
Substitute 94 for x in

Because x is not defined, it is assumed to be the height of the balloon.
Note that
75° 20' = 75.333°
49° 30' = 49.5°
From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x
Because a + b = 400 ft, therefore
0.8541x + 0.2617x = 400
1.1158x = 400
x = 358.49 ft
Answer: 358 ft (nearest whole number)
