Answer:
15 lb
Step-by-step explanation:
let the current weight of the puppy be X, the initial weight of the puppy is 4lb or [tex]\frac{2}{3}X-6\ lb[/tex], (6 lb less 2/3 X) .
#We equate the current weight to the initial weight to determine X:
[tex]4\ lb=\frac{2}{3}X-6\ lb\\\\10 \ lb=\frac{2}{3}X\\\\X=15[/tex]
Hence, the current weight of the puppy is 15 lb
