Answer:
115% of 75 is equivalent to 75 by 1.15 = 8.625 , This two are equivalent 
Step-by-step explanation:
Given as :
Tyson multiplies 75 by 1.15 
I .e 75 × 1.15 = 86.25
Now A ) 115% of 75 =  × 75 = 86.25
 × 75 = 86.25
B) 15% of 75 =  × 75 = 11.25
  × 75 = 11.25
C) 11.5% of 75 =  × 75 = 8.625
 × 75 = 8.625
D) 1.15% of 75 =  × 75 = 0.8625
 × 75 = 0.8625
∵ 115% of 75 is equivalent to 75 by 1.15   ,  so Tyson try to find the option A

I hope u understand the solution.
 
        
        
        
(-4,4) (2,1)
gradient = (1-4)/(2--4) = -1/2
y = mx + c
y = -1/2x + c
Replace point (2,1) in the equation
1=-1/2(2) +c
c = 2
Equation : y = -1/2x + 2
y-2 = -1/2x 
Answer is C.
Hope it helped!
