Answer 1

The correct question is:

How much does Sandy’s dog weigh?

Answer:

23 pounds

Explanation:

Weight of Mary's dog = 81 pounds

Let the weight of Sandy's dog be x pounds

According to the given statement:

"Sandy’s dog’s weight is equal to 4 pounds less than 1/3 of Mary's dog’s weight"

So,

Sandy’s dog’s weight(x) = 4 pounds less than 1/3 of Mary's dog weight(81)

i.e.

`x=(1)/(3)(81)-4 \\\\ x=27-4\\\\ x=23`

So, weight of the Sandy's dog is 23 pounds.
