Answer: $84
Step-by-step explanation: 20% of 875=175; 175+875=1050; 8% of 1050=84, so your final answer would be $84.
 
        
                    
             
        
        
        
Answer:
 B. 40 meters
Step-by-step explanation:
— Estimating
The rectangle enclosing the path has sides of length 9 m and 14 m, so its perimeter is 2(9+14) = 46 m. The distance covered will be shorter than that.
The distance from A to C is longer than the distance from D to C, so we know the distance will be longer than 2·14+9 = 37 m.
Only one answer choice fits in the range 37 < d < 46.
____
— Detailed calculation
The distance from B to C is the hypotenuse of a right triangle with sides 9 and 12. You will recognize that these side lengths are 3 times the side lengths of a 3-4-5 right triangle, so the hypotenuse distance is 3·5 = 15 meters.
The circuit length is ...
 AB +BC +CD +DA = 2 + 15 + 14 + 9 = 40 . . . . meters
