Answer:
11 memberships 
Step-by-step:
Gym 1 = 75+5m
Gym 2 = 50+7.5m
75+5m=50+7.5m
-50 from both sides
25+5m=7.5m
-5m from both sides
25=2.5m
divide both sides by 2.5
10=m
for 10therefor 75+5m<50+7.5m he must sell 11 memberships.
        
             
        
        
        
M=3 therefore y is slanted right downwards
        
             
        
        
        
Absolute value of any number is always positive because it represent distance and distance will always positive.
To place chimney at  least 30 feet , the distance along the width of the roof  (x) will be  x = 17.5 feet or x = 2.5 feet.
Since, The height of the roof is described by the function f(x)=−4/3|x−10| + 40
Since, minimum height is 30 feet.
So , substitute f(x)=30 in above expression.
                  30=−4/3|x−10| + 40
                    4/3|x−10| = 10
                       |x−10|=30/4
                       |x−10| = 7.5
Taking positive case,
                            x−10 = 7.5
                            x = 17.5 feet
Taking negative case,
                           x−10 = - 7.5
                           x = 10 - 7.5
                           x = 2.5 feet
