As given, Ben is walking with three dogs that weigh an average of 75 pounds each. Ben begins to walk with a fourth dog, and the average weight of the dogs decreases to 70 pounds.
The total weight of the first three dogs is 225 pounds.
This amount, plus the weight of the fourth dog, divided by total number of dogs, is the new average weight:
[tex]\frac{d+225}{4} = 70\\d + 225 = 280\\d = 280 - 225\\d = 55 lbs[/tex]
Therefore, the weight of the fourth dog is 55 lbs.
