Answer:
The equation for a is 
The altitute is 101,428.57 feet
Step-by-step explanation:
You know that the relationship between ground temperature and atmospheric  temperature can be described by the formula 
t = -0.0035a +g
where:
- t is the atmospheric  temperature in degrees Fahrenheit
- a is the altitude, in feet, at which the atmospheric temperature is  measured 
- g is the ground temperature in degrees Fahrenheit. 
Solving the equation for a: 
-0.0035a +g=t
-0.0035a= t - g


<u><em>The equation for a is </em></u> <u><em></em></u>
<u><em></em></u>
If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F
Replacing in the equation for a you get:


a= 101,428.57
<u><em>The altitute is 101,428.57 feet</em></u>
 
        
             
        
        
        
If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70% 
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100  => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100% 
100% - 70% = 30%
