Answer:
107%
Step-by-step explanation:
because if we look at the x-axis, Discount (%) 
and look at 35 which is between 30 and 40 
and start going up we get near 100
so
107%
or?
we use the two points and with that we find the slope first

plug in (20,62) and (10,32)
 
 
equals

simplify to 3
then we use 
y - y1 = m (x - x1)
y - 62 = 3 (x - 20)
y - 62 = 3x - 60
add 60 from both sides
y - 2  = 3x 
add 2 to both sides
y=3x+2
then plug in 35
y= 3(35) + 2
which is 
107
 
        
                    
             
        
        
        
Assuming the frame is rectangular, the perimeter is 2*width + 2*length. so 5*2 + 2*length = 24. subtract ten from both sides to get the 14 = 2*length. the length = 7.
